Everything about Black Label Society begins with the riff. A dedicated disciple of Zeppelin, Sabbath, and Deep Purple, Zakk Wylde looks to the massive guitar hooks in classics like "Whole Lotta Love," "Into the Void," and "Smoke On the Water" as guiding lights. "The main ingredient in any Black Label soup is the riff," says the larger-than-life frontman. Black Label Society builds their music on this simple truth, truth as self-evident on Back in Black as on the dozen songs comprising Doom Crew Inc., the eleventh album from the dependable stalwarts. Doom Crew Inc. Is both a tribute to the band's "first to bleed, last to leave" road crew and a salute to the legion whose support, stretching back to 1998, rivals that of the KISS Army. The Black Label Society biker-style battle vest "kutte" is as ubiquitous at hard rock and metal shows as a black t-shirt.
