Aftermath, released April 1966 by
Decca Records, is the fourth British studio album by
the Rolling Stones. It was released in the United States in June 1966 by
London Records as their sixth American album. The album is considered an artistic breakthrough for the band: it is the first to consist entirely of
Mick Jagger/
Keith Richards compositions, while
Brian Jones played a variety of instruments not usually associated with their music, including
sitar,
Appalachian dulcimer,
marimbas, and Japanese
koto, as well as guitar, harmonica and keyboards, though much of the music is still rooted in
Chicago electric blues. It was the first Rolling Stones album to be recorded entirely in the US, at the RCA Studios in California, and their first album released in true stereo.
