Tom Petty will appear in a documentary called Sound City which tells the story of a famous recording studio in Los Angeles.  In a clip released by the movie's makers, Petty talks about his first musical memory and influence.  It involves a man who was a major influence on a lot of child rockers of the 1950s and 1960s, Elvis Presley.

Sound City is a film produced by Foo Fighters front-man and former Nirvana drummer Dave Grohl.  Grohl has assembled countless musicians to talk about the studio which housed the recording of some of rock's most influential albums including several of Petty's.
