|Demo by Rivers Cuomo
||2020 (partially released)
The Yeastmaster is a cassette compilation by Rivers Cuomo, featuring demos recorded from 1990 through 1992. The compilation was partially released as a part of the digital compilations Alone V: Before Weezer and Patrick & Rivers in 2020.
The Yeastmaster is a demo consisting of Yeastmaster parts 1 and 2. Yeastmaster Part 1 was first mentioned by name by Karl Koch in the Recording History. Songs from Yeastmaster Part 2 are named by Koch, however their inclusion on the demo was not stated. Both demos were included on the 2020 compilations Alone V: Before Weezer and Patrick & Rivers.
These songs feature a focus on songwriting, something Cuomo's previous tapes were not entirely focused on. This resulted in songs that Karl Koch described as "either somewhat bitter or really goofy." And while there is a focus on songwriting, there are also several things that Karl described as "not-really songs".

"instrumental 1", "reggae feel", "i v ii III", "Bushman", "Bored and Boring", and "Lethargic and Lethargicing" also appear on this tape, but the track positions of the songs are unknown
