"All I wanted was a Pepsi"
Cypress Hill was, at the time, a DJ/Producer, and two MCs. Sen Dog is the lower pitched voice, who only gets half a verse on this track. It's a real fast half verse. B-Real is the one with the exaggerated nasal sound to his voice. He does two and a half verses and most of the chorus. Lyrically, the song is about weed and killing. Released over a year before The Chronic, this song, and the eponymous first album by Cypress Hill really paved the way for the weed+violence+great samples that were the hallmarks of early 90s West Coast Rap.
The samples include a guitar solo by Jimi Hendrix on Are You Experienced, the intro organ from Come On In by The Music Machine, drums from Midnight Theme by Manzel and a bass line from Lowell Fulsom's Tramp. Around 2:00 the just let the loop run for a while, and you think they are going to fade out. We get an sax solo for a while that really seems to seal the deal that the song is over. But instead, they start another loop entirely and B-Real begins his last verse over it. Then they swap back to the old loop to finish the song out. It does do the fade out we were expecting back around 2:25-2:40.
