Nirvana's rare 1992 EP Hormoaning is slated to be reissued on Record Store Day, April 16. The EP was originally sold on the group's 1992 Australian tour, and features three cover tracks of songs by Devo, Wipers and The Vaselines and two originals, "Aneurysm" and "Even In His Youth." Four of the six tracks eventually found a wider release on the group's 1992 compilation Incesticide.
