The Mushroom River Band is a stoner metal band founded by guitarist Anders Linusson, bass player Alexander "Saso" Sekulovski and drummer Andreas Grafenauer in 1996. This line-up recorded one demo tape with Christian "Spice" Sjöstrand from Spiritual Beggars as a guest singer. In 1997 Chris Rockström took over on drums and Spice joined full-time as a singer along with his duties in Spiritual Beggars. A vinyl EP called 'Rocketcrash' was released in 1999 on the band's own Tea Pot Records label.
