It’s 10:30 on a bitter cold Friday night in Davis Square and there’s a line extending down Elm Street outside The Burren. The reward for bearing the 19° January cold is to pay three dollars for three hours of one of the best alt-country/rock performers you’re ever going to see—Jabe. It is hot and packed in the back room where Jabe and his band--consisting of bass, drums, and mandolin, with Jabe on guitar—are already at full throttle slinging Jabe’s Tom Petty/Bob Dylan meets The Charlie Daniels Band brand of music. This is not one of your typical scenester shows wre the audience is too cool to get up close during the first set and dance. No, the room is really swinging, everywhere. As drinks are spilled and coats are shed, Jabe brings it on, playing their homemade instruments, which really seems to suit this band’s homemade feel. The songs seem unstructured or unpracticed: Jabe continually nods to his band when a song ends or a solo begins, but that somehow adds to the theatrics. There are lots of bands that play with feeling but few that make you feel. Jabe does both. Jabe begins the last set with a couple of rockers to let everyone know that this show isn’t going to slow down yet. One of the songs starts out like Hendrix’s “Foxy Lady” and Jabe continually switches musical hats in the last hour; going through rock, rockabilly, and alt-country. All the girls up front are hanging on his every word through his ballad “Maybe Next Time,” and then, just like that, the show ends, making a three-hour set seem like a half hour.
