Brothers Jamin and Jesse Marshall formed the group in 2003 beginning as a 3-piece punk rock band with Greg Johnson. The name Larry and His Flask comes from a fictional character created by Jamin Marshall around the time of the formation of the band. With Jesse Marshall playing electric bass at the time and Jamin Marshall on drums Greg Johnson played electric guitar and were soon joined by Ian Cook who played lead guitar. The next addition was another long-time friend Beau Batts replacing Jamin on drums bringing him to the front as lead vocalist. According to the band they, "spent its first half-decade stuck in a primordial, punk-rock goop" where the goal was always "party over perfection." During this time a number of albums were self-released with different line ups. The most consistent at that point being Jamin Marshall, Jesse Marshall, Ian Cook, Beau Batts and Brian Martin from 2005-2007. In this time The Lost Seamen and We're Going Dancin' Tonight were released and short tours around the surrounding states with another local band, Zombie Co-Pilot, were commonplace. Brian Martin then left, leaving Ian as the sole guitarist. Continuing as a quartet, they continued to tour, also playing a date at the 2007 Vans Warped Tour. The next full-length release was Never Long Gone! in mid-2008, with their first full Canadian tour. However, not long after arriving back home, Beau Batts also left the band. In late 2008, the band radically changed its sound. They switched to acoustic instruments and guitarist Ian Cook took over lead vocals, moving original vocalist Jamin Marshall back to drums. While changing the dynamic within the remaining members, guitarist Dallin Bulkley as well as mandolinist Kirk Skatvold and banjoist Andrew Carew from the now defunct Zombie Co-Pilot were recruited, as well as others from more local bands, adding multi-part harmonies to its punk rock roots to round out the new sound. It was at this point that LAHF grew to 11 members for a short time with the addition of an accordion, fiddle, and cello among other instruments before coming to the 6 that are now the current members. The band's first full-length since this stylistic change, 'All That We Know'', was released by [Silver Sprocket Bicycle Club in July 2011. Larry and His Flask performed on the entire 2011 Vans Warped Tour and toured in support of Streetlight Manifesto in 2011. "The Flask" is set to tour with Pentimento recording artist Lionize from September through November 2011. After appearing on the final leg of the 2012 Warped Tour, Larry and his Flask toured with international recording artist Frank Turner on his 2012 US tour and his 2013 UK tour. In June 2014, while on tour, they had their van and equipment totaling $24,000 stolen in Cayce, SC.
