4. Aerosmith
Aerosmith had its ups and downs within the band, dealing with drugs and almost derailing completely, but they stayed intact and made a name for themselves as one of the all-time best. No other band touched them in producing blues-based hard rock. Aerosmith is the best-selling American hard rock band of all time. They sold more than 150 million records worldwide, with over 70 million records in the United States alone.
