[ rock/blues ] 
On his latest effort, The Secret (Six Degrees), guitarist/singer Vieux Farka Touré jams with several famous friends, including Dave Matthews, Derek Trucks and Ivan Neville. But at the core of the album is the combination of transcendent Malian grooves inherited from his late father, Ali Farka Touré, and hard-edged rock, blues and soul influences. It will be that sound, fueled by his intricate, entrancing guitar work, that will undoubtedly be broadcast to West Philly passers-by during this show, the second in this year's 40th Street Summer Series.
Sat., Aug. 27, 6-8 p.m., free, with Kyo Daiko, 40th Street Field, 40th Street between Walnut and Locust, 215-243-0555, universitycity.org.
