The Soulive, which played later Friday night, really was exactly what a jam-band should be. The band members traded long melodic solos that packed a punch full of funk and groove, and they knew how to build a song by playing with the dynamics, tempo shifts, and including plenty of hooks. The audience that filled East Avenue to see the band perform dug what it heard, and the band fed off that energy and gave the listeners (and plenty of dancers) a large dose of back beat to shake their hips to. It was impressive to see that in the roughly eight years since tunes like "Steppin'" have been released, they've become something like new standards that people know instantly. Soulive started the night with that song, and the audience reacted much how I'd expect a 1950's jazz crowd would have to Miles Davis playing "Bye Bye Blackbird."  Simply put, the fans hung on every note -- even through the rain.
