TV singing competitions such as American Idol and The Voice have changed the way talented singers seek stardom, but one veteran rocker admits he’s not fan of the impact these television talent shows have had on the music business.

“I don’t want my kid to think that the only way you can be a musician is to stand in line at a song contest audition, and then wind up having a bazillionaire tell you you’re not a good singer,” said Foo Fighters front man Dave Grohl during a Thursday-afternoon session at the TV Critics Association summer press tour, currently underway in Beverly Hills. “Don’t get me started,”; added Dave. “To me, that’s not what music’s about.”

Dave was on hand to promote his upcoming HBO docu-series Sonic Highway, in which he and the Foo Fighters travel to eight different American cities to record their new album, heading to an iconic recording studio in each city to record one song that’s reflective of that particular city’s musical influences.

As he explained, this ambitious project is “all about reinventing the process,”; he said. “We could just go and make another record in the studio, hit the road and sell a bunch of T-shirts … but where’s the fun in that?”

Dave Grohl’s Sonic Highway is due to debut in November.
