The Beastie Boys’ “Intergalactic” samples the theme music for the 1985 film The Toxic Avenger, as adapted from Rimsky-Korsakov’s arrangement of Mussorgsky’s A Night on Bald Mountain. The sound effect sample originates from the sound the Resonator makes in the 1986 film From Beyond. Elements of Les Baxter’s rendition of Prelude in C# Minor as composed by Rachmaninoff are also used during the verses, and the song also contains elements of the Jazz Crusaders album Powerhouse. Throughout the song, a heavily vocoded voice repeats, “Intergalactic, planetary, planetary, intergalactic; another dimension, another dimension.” The closing “Do it!” is sampled from the 1971 Stovall Sisters song “Hang on in There”.
But strip all the samples and instruments away, and you still have one amazing performance.
