It features Syd Barrett-era Floyd performing its barnstorming signature tune, "Interstellar Overdrive," and what sounds like an embryo version of "Set the Controls For the Heart of the Sun," from A SAUCERFUL OF SECRETS, here called "Nick's Boogie." Both songs included here are epic-length improvisatory pieces that shift from spacy ambience to full-blown freakout and back again, using very basic tools. Synthesizers hadn't come on the scene yet, so Rick Wright relies strictly on his snake-charmer organ riffs to enhance the spooky, ethereal mood. Barrett utilizes pure, acid-drenched weirdness to make the most unearthly sounds possible with very little electronic enhancement. Legions of groups would take their cue from the advances made by Pink Floyd during this time, and LONDON makes it easy to see why.
