Bryan Josh (born 1967) is a multi-instrumentalist who is the founder of British progressive rock band Mostly Autumn. While primarily being the band's lead singer (previously with Heidi Widdop and Heather Findlay, and presently with Olivia Sparnenn) and lead guitarist, he has performed on many other instruments in the studio, which include the bass guitar, piano and keyboards. He, either alone or with other members of the band, has written a large percentage of the band's back catalogue. He also contributed to Mostly Autumn keyboardist Iain Jennings' solo album, Breathing Space where he played two guitar solos.
