For power, grace, indelibly monstrous riffs, and acidic Sturm und Drang arrangements of blues songs, Led Zeppelin were damn near unparalleled. Drummer John Bonham's death in 1980 ground the juggernaut to a halt, but the lust for Zep's music continues unabated to this day. Which opens a door of opportunity for a tribute group like the Chicago-based Led Zeppelin 2. These guys have LZ's sound down to an artful science, plus the singer—Yakuza's Bruce Lamont—even keeps his shirt unbuttoned onstage (details are important!). Guitarist Paul Kamp mimics Jimmy Page's excoriating flourishes with panache, Matt Longbons embodies John Paul Jones's quietly spectacular contributions on bass and keyboards, and drummer Greg Fundis replicates Bonzo's dexterous bludgeoning—and he has a gong. Good times (probably not bad times). by Dave Segal
