A comienzos de 1990, Nirvana empezó a trabajar con el productor Butch Vig para grabar el segundo álbum de estudio, titulado provisionalmente Sheep.7 Durante las sesiones, Kurt y Krist coincidieron en que Chad no era el batería que necesitaban, y en un acuerdo mutuo éste dejó la banda después de finalizadas las sesiones. Dale Crover entró como reemplazo temporal de Channing, tocando 8 recitales con Nirvana en 1990. Después contrataron al batería de Mudhoney Dan Peters, con quien grabarían el sencillo "Sliver", además de tocar en un solo concierto en el Motor Sports International Garage de Seattle el 22 de septiembre de 1990. Posteriormente el mismo año, Buzz Osborne de The Melvins les presentó a Dave Groh
