Aerosmith posted a previously unreleased song called "Movin' Out" from 1971 on YouTube. The song is included on ‘Aerosmith—1971:The Road Starts Hear,’ a limited-edition vinyl and cassette release set for Record Store Day next week on November 26th.
The tape was only recently discovered in Aerosmith’s vault and it includes very early versions of “Dream On,” “Walkin’ the Dog” and “Mama Kin.”
The songs were recorded on Joe Perry’s Wollensak reel-to-reel tape machine either in the band’s Boston rehearsal room or at a rehearsal during a sound check for an early show.
