Mostly Autumn is a British band, producing music heavily influenced by classic 70s rock, most obviously Genesis and Pink Floyd, and folk music. More recent albums have also included more contemporary influences.

Mostly Autumn was formed in the late 1990s. The line-up that recorded their first album was Bryan Josh, Heather Findlay, Iain Jennings, Liam Davison, Bob Faulds, Stuart Carver, Kev Gibbons and Allan Scott (see the Members section for more details).

On their second album Allan Scott was replaced by Rob McNeil and for their third album (2001), he in turn was replaced by Jonathan Blackmore, while Andy Smith replaced Stuart Carver on the bass guitar and Angela Goldthorpe joined to provide flute and backing vocals. In 2004, shortly before the band's 'V Shows' tour, Iain's brother, Andrew Jennings, took over on drums and percussion. Olivia Sparnenn joined the band in 2005 to provide additional backing vocals.

Iain Jennings left the band at the beginning of 2006 to pursue his own musical ambitions and has put together his own band, Breathing Space, as well as contributing to projects by other artists. Breathing Space have so far released two albums: Breathing Space (2005) and Coming Up For Air (2007). Iain also recruited Olivia Sparnenn to provide lead vocals although she continued to be a member of Mostly Autumn and performs with both bands.

Ben Matthews of Thunder stood in on keyboards for the band's headline gig at the Baja Prog Festival in Mexico in March 2006. Chris Johnson was then recruited as a permanent replacement, with Angela Gordon (formerly Goldthorpe) also taking a more prominent role on keyboards.

At the beginning of 2007 both Liam Davison and Andrew Jennings left the band, Liam to concentrate on his solo album and Andrew to devote his time to his other projects. Ex-Karnataka and Fish-drummer Gavin Griffiths stood in on drums for most of the 2007 live shows, but the band decided not to replace Liam Davison, preferring to either adapt the songs as necessary or use Chris Johnson or Heather Findlay for additional guitar duties as appropriate. Andrew Jennings temporarily rejoined the group at the end of 2007, until Henry Bourne took over in 2008. Gavin Griffiths returned for the first shows of 2009 in Manchester and London.

When Chris Johnson and Angela Gordon left in 2008, Iain Jennings and Liam Davison returned to the fold on keyboards and guitar respectively. Anne-Marie Helder, who has occasionally played support slots to the band in the past and who also filled in for Angela during her pregnancy, has taken over the role of flute, keyboards and backing vocals.

A new studio album, entitled Glass Shadows was released in 2008 and an accompanying tour took place in spring and early summer 2008. A 100-minute DVD, 'The Making Of Glass Shadows', accompanied the special pre-order version of the album.

During October 2008 Mostly Autumn performed two gigs with an alternative, semi-acoustic line-up in support of the Bad Shepherds. The line-up consisted of Bryan Josh (guitar and vocals), Olivia Sparnenn (on lead vocals due to Heather Findlay being unavailable as she'd recently had her first baby), Andy Smith (bass), Anne-Marie Helder (keyboards and flute) and Robbie Baxter (normally their drum technician but standing in for Henry Bourne). Originally the band had been scheduled to play a large number of gigs on the Bad Shepherds tour but this didn't come to fruition as the Bad Shepherds postponed or cancelled many dates.

In 2010 Heather Findlay left the band to go solo. The backing vocalist Olivia Sparnenn took over te lead and how. The audiences were flabbergasted about the clearness and stage performance. The band is on fire as never before and eager to prove that they can survive. And if we believe the reviews of the last gigs; they do!
