CORRECTION: A previous post announced Alejandra O'Leary as this week's performer, but O'Leary is scheduled to play July 13.

The AnnArbor.com Summer Concert series this week showcases a longtime pillar of the local jazz scene, the Paul Keller Quartet.

Keller is a bandleader, musician, composer, and operator of his own independent record label with extremely deeps roots in the local jazz community. For more than two decades, his big band, the Paul Keller Orchestra, has had a regular Monday night gig around town: It started as the Bird of Paradise Orchestra in the old Bird of Paradise Jazz Club, moved to the Firefly Club as the Paul Keller Orchestra, then stopped at Keystone Underground and most recently plays at the Zal Gaz Grotto Club.

Keller, a master string bass player, also performs regularly in a quartet format, which is the plan for Friday. His label, PKO Records, has produced his own albums as well as recordings by other notable local jazz musicians; in addition, Keller has played as a side man on more than 60 albums by other acts, including major names like Diana Krall.

For more information on Keller, see the PKO Records website.

The Paul Keller Quartet will play at noon Friday, June 8 on the patio of the AnnArbor.com Community Space at 301 E. Liberty Street, at Fifth Avenue. The AnnArbor.com Summer Concert Series continues at noon Fridays throughout the season; check out the website for more information.
