Released in 1976, Rocks is Aerosmith's fourth studio album and one of their most influential. Stylistically, the album has a harder edge than later releases, appealing to more blues and hard rock fans. It has been a very influential album to heavy metal and rock musicians of later generations, including Kurt Cobain and Guns N' Roses. Rocks produced the Aerosmith classics "Back In The Saddle" and "Last Child".
