Carlos Santana has a lot on his plate these days: He's launching a chain of Mexican restaurants, appearing in Macy's commercials to hype the line of women's shoes he has designed, and advocating a national holiday to honor labor leader César Chávez. But he still finds time now and then to play a bit of guitar. Santana's records over the past decade have focused on his collaborations with various pop, rock, and hip-hop musicians, but his live show still includes many of the fiery, percussion-heavy jams — such as "Jingo" and "Incident at Neshabur" — that back in the day helped burn his signature sound into the public consciousness, abetted by a superlative band featuring jazz/funk drumming giant Dennis Chambers and longtime keyboardist Chester Thompson.
