Murry The Hump was formed in Aberystwyth, Wales, in 1999 by vocalist Matthew Evans, guitarist Gwion Rowlands, bassist Curig Huws and drummer Bill Coyne, taking their name from gangster Llewellyn Morris “Murray The Hump” Humphreys. Their first commercial breakthrough came with the 1999 single "Green Green Grass of Home" on Blue Dog/V2, earning NME “Single of the Week” status, followed by "Thrown Like a Stone" on Shifty Disco, which placed ninth in John Peel’s Festive Fifty that year; the band also recorded three Peel Sessions and gained support from BBC Radio 1 DJs Steve Lamacq and John Peel. In 2000 the band signed to Too Pure, released the split single "The House That Used to Be a Ship" with Hefner, then the EP Cracking Up (2001), named a Track of the Year by the Sunday Times, and the album Songs of Ignorance (2001), praised by The Independent and the NME. The group toured the UK with Hefner and performed at the BBC Radio 2 Live in Cardiff festival in October 2001 before announcing their split in September 2001. After the breakup, Matthew Evans, Gwion Rowlands and bassist Siôn Glyn re‑emerged as The Keys in 2002, releasing a self‑titled album in 2003 and later albums Fire Inside (2010), Bitten by Wolves (2011), Ring the Changes (2014), Bring Me the Head of Jerry Garcia (2019) and Home Schooling Album (2020).
