Happy 75th birthday today to guitarist and Aerosmith co-founder Joe Perry (born 9/10/75). Perry’s cool style, riffs, and solos propel Aerosmith classics like “Walk This Way,” “Sweet Emotion,” “Last Child,” and “Back in the Saddle,” and all the other B-sides that never got the radio play they deserve. Watch Aerosmith at their most dangerous (onstage and off) in 1978 at Texas Jam.
