MCIS Demos I

MCIS Demos I (later released as Billy's Home Demos) is a non-commercial bootleg album of The Smashing Pumpkins. It was the first set of demos to circulate in 1996 and offers the earliest known recordings for Mellon Collie and the Infinite Sadness. All tracks are demos recorded in Billy's home studio, Sadlands. Four songs ("Jupiter's Lament", "Blank", "Rotten Apples" and "Meladori Magpie") are identical to the B-sides that were later seen on official releases.
