"Ego Trippin′" is a 1986 song by Ultramagnetic MCs. The group made a stylistic breakthrough with it; the song boasted dense, minimalist production, featuring erratic lyricism by Ced-Gee and Kool Keith, synthesizer riffs and was the first song to sample Melvin Bliss's "Synthetic Substitution", now one of the most sampled songs of all time.
