Being released in February of 93' "Oh The Guilt" become somewhat a forgotten Nirvana song after the release of this split single. Upon entering the next decade it'd be resurfaced in the longly anticipated "With The Lights Out" Nirvana Box set(released in Nov. 2004). Also noted you can hear this song on the WTLO compilation
"Sliver:Best of the Box" (released in Nov. 2005) Great song, kind of rough recording wise.
("Oh The Guilt" was originally recorded previously in April of 92')
Along with "Oh The Guilt" comes The Jesus Lizard song "Puss". While not so much a rarity as it's available on their (Oct. 1992)third release "Liar" did achieve chart success from the single, but controversy from the music video. The song is still non the less a great song. TJL are a bit less mainstream than Nirvana, and have a more Punk orientated sound.
Oddly enough Steve Albini produced "Puss", later Albini would go to work on Nirvana's third and final studio album "In-Utero".
I'd say buy this only if you're a Nirvana music collector.
