Before they made major waves with Nirvana and Foo Fighters, Dave Grohl and Pat Smear shook up the underground as members of hardcore bands Scream and the Germs, respectively. They dive back into the CBGB-matinee mosh pit with Teenage Time Killers, a new all-star project including current or former singers from Slipknot, Lamb of God, Dead Kennedys and Fear. Though Grohl (who played bass and lent his 606 Studios to the cause) and cohorts are far from their teenage years, Greatest Hits Vol. 1 rarely sounds like old guys trying to relive their pissed-off youth. Rather, it sneers and snarls like a long-lost punk mixtape, fueled by the forever-young rage of rockers who refuse to grow up.
