"Shapes of Things" is a song by the English rock group the Yardbirds. With its Eastern-sounding, feedback-laden guitar solo and anti-war/pro-environmental lyrics, it "can justifiably be classified as the first psychedelic rock classic", according to music critic Richie Unterberger. The song was built on musical elements contributed by several group members in three different recording studios in the US. When it was released as a single on 25 February 1966, it was their first composition to become a record chart hit. The song reached the pop Top 40 in several countries, but, aside from compilations, was not included on a Yardbirds' album.
