The Vulgar Boatmen got attention three or four years ago with what even in hindsight strikes me as one of the best records of the 1980s. You and Your Sister is a lovely acoustic-based set of moving and riveting songs that traverse two territories: a scarred but healthy emotional one of loss, love, and desire and a musical one that contains a mini history of American blues, country, and rock 'n' roll. In the record's wake the band established a touring base in the midwest but were ignored in most of the rest of the country. Last year's Please Panic lacks to my ears the dramatic atmospherics of the first album, but it's still an extremely impressive cycle of heartfelt songs and unadorned, respectful instrumentation. The show Saturday is significant in that it reunites the band with one of its founders, Walter Salas-Humara, who went on to lead the Silos but has remained close to the band and has helped produce its albums. Look for an opening acoustic set by Salas-Humara, a few more songs with the Boatmen sitting in, a full Boatmen set, and then a few more numbers with Salas-Humara. Saturday, Elbo Room, 2871 N. Lincoln; 549-7700.
