For rock music in the early 1970s, the possibilities seemed endless. The people who played it wore their hair long and their flares even longer as they belted out a loud, proud noise they thought would echo forever. Almost Famous, the film from US writer- director Cameron Crowe, lets us in on just how close they came to getting it right. As a teenage music journalist about 30 years ago, seasoned road- warrior minstrels such as Led Zeppelin and the Stones would take him on tour with them, and Crowe would chronicle every high point and bum note. Almost Famous is a deeply personal tale, set in the days when Crowe was music’s Macaulay Culkin starring in his own version of On the Road Alone.
