Feeling like one shaggy dog story after another, Sex Packets forever put Digital Underground on the map thanks to the fluke smash hit “The Humpty Dance,” itself a perfect follow-on from the previous “Doowutchyalike” single. But the whole was inspired hilarity and musical skill in equal measure, main figure Shock G taking his overwhelming P-Funk love and bringing it to hip-hop in full, resulting in songs both mesmerizing and hilarious like “Underwater Rhymes,” as well as local Bay Area in-jokes like “Gutfest ’89.”
