On Dutch and German pressings of the album, the title is listed as "The Rolling Stones Vol.  2" on the front cover, although the back of the album cover lists the title as "The Rolling Stones No. 2".

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.
