Side 3 is the third album from the Raspberries, released in 1973 (see 1973 in music). The album cover is cleverly shaped like a basket of Raspberries, with the group's name placed on top of the LP sleeve. Three singles were released from the album: "Tonight", which reached number 69 on the US Billboard Hot 100 and number 37 on the Cash Box chart; "I'm a Rocker", which reached number 94 on Billboard and number 75 on Cash Box; and a third single, "Ecstasy", which did not chart on Billboard but reached number 116 on Cash Box. The album itself reached number 138 on the US albums chart.
This album was re-released on CD as part of the Power Pop Vol. 2, also containing their fourth album Starting Over.
"Tonight" was later covered by glam metal band Mötley Crüe for their 1981 album Too Fast for Love, but the track was left out of the initial release (it later appeared in the 1999 reissue and later versions).
