Additional Info:

Sometimes referred to as "The Bad Boys from Boston" or "America's Greatest Rock and Roll Band," the Boston, Massachusetts based band Aerosmith, has been rocking out ever since their formation in 1970. Whether it was for hearing them play their driving, blues-based rock classics such as "Mama Kin," or seeing Steven Tyler get behind a grand piano and play "Dream On," Aerosmith was the band to see in the 1970s.
