The sound is Norwegian hard rock, the look is Tom of Finland -- meets -- Village People, and the lyrical approach is junior-high snicker-inducing (''F -- -the World,'' etc.). Yet you can't help but take Turbonegro seriously, especially when they unshackle their melodramatic metal with such conviction. At their raunchy best -- ''Drenched in Blood (D.I.B.),'' ''Le Saboteur'' -- they gleefully bridge the gap between the Misfits' horror-show punk and Alice Cooper's cartoon sleaze.
