Philadelphia's best-named band, Algernon Cadwallader, brings spazzy, herky-jerky, rising-and-falling rock so '90s-authentic you'll think this is what the Kinsella brothers have been up to since Cap'n Jazz first set sail. Spazzier Pennsylvania neighbors Snowing and 1994 open. Admission $5. 10 p.m. Tuesday. Dragon's Den, 435 Esplanade Ave.
