Dave Grohl stands up for lo-fi rockAdd to Favorites | American Idol
"The human element of making music is what's most important," said Grohl. "Actually learning to play an instrument and sing a song. It doesn't have to sound perfect."
"It's not about what goes on in a computer," Grohl continued, talking about how his band's latest album was recorded in his garage.
Grohl is also on the record as not being a fan of "Glee."
Fittingly, the next segment started with LMFAO's "Party Rock Anthem." And, later in the show, Grohl was shown rocking along in the audience to computer-assisted DJ deadmau5.
