Interstellar Overdrive

"Interstellar Overdrive" is a prime example of Pink Floyd's early Syd Barrett-driven days when they created mostly psychedelic rock. It features long, discordant chords on Barrett's guitar, constantly changing tempos, shifting rhythms, and few, or in this case, no lyrics at all.

The song is part of Pink Floyd's debut album, Piper At The Gates Of Dawn, which was digitally remastered and released in 2007 in two editions: A 2-CD set with stereo and mono versions, and a version that also contains a book and a CD with all of Pink Floyd's 1967 singles along with some alternate mixes and limited release versions.

The main riff throughout the tune was adapted from the guitar riff from Love's remake of "My Little Red Book."
