Colorado Jam Rock band Big Head Todd and the Monsters (apparently named for the outsized cranium of their lead singer and guitarist Todd Park Mohr) play a leaner, more streamlined version of Jam Rock than some of their Horde Tour brethren. The sound of the band -- which at its core is a power trio, though sometimes they augment their touring lineup with keyboards -- pivots on Mohr's bluesy baritone voice and his fluid, post-Stevie Ray guitar work. The band earned their reputation and dedicated following through relentless touring. Self-released records sold into five figures, which in turn attracted major labels. The band's first major label record sold at a steady pace, buoyed by a couple of radio hits. To date, they remain a popular concert attraction.
