Californian singer-songwriter Jackie Greene plays at the Tralf tonight.  I'd never heard of him before being assigned this post, but after checking him out, I really like his music. It's catchy pop-folk at its best; his rhythmic guitar playing and lazy voice instantly draw listeners in. Greene has played with an impressive roster of musicians, and most notably, he is a member of Phil Lesh and Friends, the former Grateful Dead bassist's group. Tonight's show starts at 8 p.m., and admission is $17.
