The folks at WQKL radio, "Ann Arbor's 107one," recently put out a third volume of their album series "Live From Studio A2." Like the earlier editions, the album compiles made-in-Ann-Arbor recordings from 16 of the countless notable touring musical acts who've come through town in the last year or so.

And once again, proceeds from sales of the CD benefit one of Ann Arbor's nonprofit treasures, the Michigan Theater. Even better, the quality of the music and the production is uniformly high throughout.

Fans of WQKL's "adult alternative" format will find lots of familiar names here, including Regina Spektor, Natalie Merchant, Amos Lee, Brandi Carlile and the Avett Brothers.

One interesting things about this compilation is that despite each track featuring a different artist; despite three different venues being used (in addition to the WQKL studio, tracks were done at Borders and the Big Sky Recording studio); and despite some songs having an audience and some not; the album maintains an agreeable consistency of atmosphere. Even though some of it's uptempo, this isn't music to rock out to; it's kick-back, relax-with-a-refreshment music. The vibe is relaxed and the instrumentation acoustic.

Of course, different tracks will appeal to different listeners. For me, Stephen Kellogg and the Sixers' "4th of July" is the best cut here, a terrific, affecting song, compellingly played, practically packing an entire world view into its 5-minute length. Ingrid Michaelson's energetic version of the memorable "Maybe" is a close second.

Ani DiFranco's "Present/Infant" is another highlight, nicely demonstrating her continuing appeal as she matures as an artist. And "Rusty Wing," the lively and engaging contribution here from regional favorites Steppin' In It, makes me renew my determination to start paying more attention to them.

I used to like John Gorka a lot, but I haven't really kept up with him; his "Ignorance and Privilege" here is a remarkably self-reflective piece of songwriting, and he sounds as good as ever. Likewise, it's always nice to hear something from Jonatha Brooke, and the album contains a nice treat from her — "Sweetest Angel," from her project setting unused Woody Guthrie lyrics to her music.

Any individual listener probably won't like every song on the album. But if you enjoy 107one at all, you'll probably like the bulk of it. This series is a welcome addition to the local music scene, and serves a good cause too. I look forward to Volume 4.

The CD is available for the holidays at the Michigan Theater Guest Services desk and at Borders stores in Ann Arbor, Brighton, Canton and Novi. The cost is $12.99.
