The Ann Arbor Summer Festival this morning announced its main-stage schedule of ticketed shows for the year, with highlights including k.d. lang, Steve Martin (playing bluegrass), Trombone Shorty and more.

Other acts include Andrew Bird, Los Lonely Boys, Pink Martini and traditional favorites Capitol Steps. Take a poll on what looks most interesting at the end of this post.

Although the Top of the Park lineup will be announced later, the festival did also release information on a special ticketed outdoor attraction called Amococo luminarium, a giant walk-in art installation created by England's acclaimed Architects of Air to be placed at Palmer Field.

This year's Ann Arbor Summer Festival runs June 17-July 10. It features the two traditional components: ticketed main-stage performances at the Power Center and elsewhere; and free, outdoor music and movies known as Top of the Park, held on Ingalls Mall.

Today's announcement covers the main-stage performances. Tickets go on sale to the public on Monday, April 11 at 9 a.m. through the Festival Ticket Office, 911 N. University Ave., at 734-764-2538; or online through the festival website at www.annarborsummerfestival.org. As it did last year, the festival will present slightly fewer ticketed indoor performances than in previous seasons. As with many nonprofit and arts organizations, the festival has wrestled with difficult funding issues in the down economy.

“As our audiences continue to grow at Top of the Park, we feel it’s important to introduce new activities and experiences into the environment,” Festival Director Robb Woulfe said in a press release. #8220;We’re always looking for creative ways to engage our community, so this year we’re very excited to introduce an even wider range of programs, festival partners and event venues.” The festival will host a special four-day outdoor exhibition of the Amococo luminarium, a massive walk-in art installation created by England’s acclaimed Architects of Air. The biggest of the company’s luminaria, the approximately 10,000-square-foot inflatable structure will make its Michigan premiere on Palmer Field, on Washtenaw Avenue, a short walk from the Top of the Park site, from June 23-26. Amococo is a large-scale, inflatable sculpture consisting of tunnels, domes and atriums. Tickets for this interactive family attraction will only be available at the luminarium entrance on Palmer Field during the four days of exhibition. Admission is $5 per person; children 3 and under free. The Top of the Park lineup will be unveiled at a special announcement party hosted by Arbor Brewing Company on May 2 from 5-8 p.m. The free public event will also serve as the launch for a special, limited-edition seasonal beer, Festival Saison, developed in partnership between Ann Arbor Summer Festival and Arbor Brewing Company. The new summer ale will be sold exclusively at Arbor Brewing Company throughout the summer months, with a portion of sales proceeds going to support Top of the Park. Main-stage lineup Following is the full lineup of ticketed events, with descriptions provided by the festival:

ANDREW BIRD With special guest Haley Bonar Saturday, June 18 Power Center | 8:00 p.m. $45, $40, $35, $30 Folk | Rock | Indie Few artists better exemplify the term chamber pop than violinist, whistler, songwriter, and multi-instrumentalist Andrew Bird. A classically trained violinist, former swing jazz musician and now art rock virtuoso, Bird is one of the most imaginative and distinctive voices making music today. Essentially a one-man band, Bird plays and layers live loops, stacking sounds and rhythms, and offering an eclectic mix of Gypsy ballads, jazz, folk and rock. Opening set by indie singer-songwriter Haley Bonar. TROMBONE SHORTY & ORLEANS AVENUE With special guest The Macpodz Tuesday, June 21 Power Center | 8:00 p.m. $35, $30, $25, $20 New Orleans Jazz | Funk | Soul Equally adept on the trombone and trumpet, Troy “Trombone Shorty” Andrews is a man to be reckoned with on both. He draws unqualified respect of some of the most iconic legends in jazz and possesses the ability to deliver a high-energy funk rock show capable of mesmerizing international rock stars. Trombone Shorty and Orleans Avenue’s forward, high-octane music has become so popular that they created a tagline for it: SupaFunkRock! Opening set by jazz-fusionists The Macpodz. THE MOTH MAINSTAGE Co-presented with Michigan Radio Thursday, June 23 Power Center | 8:00 p.m. $40, $35, $30, $25 Storytelling | Spoken Word The Moth, New York's hottest literary phenomenon, is an acclaimed nonprofit organization dedicated to the art of storytelling.

LOS LONELY BOYS With special guest Alejandro Escovedo and The Sensitive Boys Wednesday, June 29 Power Center | 8:00 p.m. $45, $40, $35, $30 Blues | Pop | Rock Two of the most revered artists in American roots music — fiery Texas blues-rockers Los Lonely Boys and genre-bending singer-songwriter Alejandro Escovedo — join forces for a double-bill of emotionally charged music steeped in the rich musical traditions of Texas, the American Southwest, and Mexico, Los Lonely Boys — a potent trio featuring Garza brothers Henry, JoJo, and Ringo, sons of Texas conjunto legend Ringo Garza, Sr. — soared to national attention with their Grammy-winning debut album, recorded with country icon Willie Nelson, plus tours and recordings with mentors Carlos Santana and Los Lobos. Now the Garzas connect with another musical hero in Alejandro Escovedo, the seminal roots-rock innovator. Escovedo has virtually defined the Americana sound over the course of an esteemed 20-year solo career, infusing lyrical Tex-Mex and folk balladry with rock and classical influences.

Canadian superstar k.d.lang returns to the Hill Auditorium to headline a spectacular evening of new originals and soulful classics. The winner of four Grammy Awards and eight Juno Awards, k.d. lang's powerful, sultry vocals and astounding range have made her one of the most sought after live performers for the past 25 years. Her frequent collaborator Tony Bennett calls her "the best singer of her generation" and her performance of Leonard Cohen's "Hallelujah" at the 2010 Vancouver Olympics Opening Games was nominated for a Juno Award for Single of the Year. Touring in support of her newest release "Sing It Loud," prepare to be astounded by k.d. lang and her new band Siss Boom Bang. Opening set by folk-rock siblings The Belle Brigade.

TAYLOR MAC IN CONCERT "Comparison Is Violence or The Ziggy Stardust Meets Tiny Tim Songbook" Saturday, July 2 Lydia Mendelssohn Theatre | 8:00 p.m. $25 General Admission Cabaret | Performance Art | Fringe Recommended for mature audiences Gloriously larger than life, the fabulous Taylor Mac draws from the traditions of drag and performance art to create a style all his own. Combining dramatic flair, searing satire, poignant honesty, and—of course—plenty of glitter, Mac’s newest show, "Comparison is Violence," was born after dozens of reviewers commented that he was a cross between David Bowie’s alter ego and the cult figure Tiny Tim. While praising his ukulele-playing and gender-bending performances, over 20 international publications have, of their own volition, described Mac as ‘Ziggy Stardust meets Tiny Tim’. Being a queen who can take a hint, he decided to write and perform an original conversation about comparison, while singing Tiny Tim songs and selections from David Bowie’s classic glam-rock album "The Rise and Fall of Ziggy Stardust." It promises to be a concert unlike any other.

THE CAPITOL STEPS Monday, July 4 Power Center @ 5:00 p.m. & 8:00 p.m. $45, $40, $35, $30 Comedy | Political Satire The only group in America that attempts to be funnier than the politicians, the Capitol Steps provides an entertaining blend of musical and political comedy. Answering the call for more civil discourse, these former Congressional staffers' brilliant song parodies and hilarious sketches lampoon up-to-the-minute issues, events, and personalities, poking fun at both sides of the aisle. TOM TOM CREW Thursday, July 7 & Friday, July 8 Power Center @ 8:00 p.m. $40, $35, $30, $25; Kids $10 Circus | Acrobatics | Family Direct from sell-out seasons in New York, London, Berlin, Sydney and Edinburgh, experience a collision of super-charged circus and heart-pumping music for all ages.
