After Electrifiedshitfuck dissolved, Kurt formed Fecal Matter. The group played several concerts, including many supporting the Melvins. Two demo sessions occur before the group dissolves.
Demo 1: Kurt Cobain(guitar), Dale Crover (bass) and Greg Hokanson (drums), recorded at Kurt's Aunt Mari's house
Demo 2: Kurt Cobain(guitar), Dale Crover (bass) and Matt Lukin (drums)
No bootlegs exist of any concerts, but they are known to have played at the Spot Club in Moclips, WA some point in December 1985.
Note that most of the members were also in the Melvins, and that the Melvins recorded their first LP in February of 1986, right after Fecal Matter dissolved.
