When Michael Davies, one of January Thirst's original vocalists, quit in December 2001, Matthew Evans (vocals) and Johnny Phillips (drums) invited Matt Davies (later Davies-Kreye) to try out for the vacated singer position. Soon afterward, the band reformed as Funeral for a Friend; the name is derived from a song by Planes Mistaken for Stars, one of Davies' favourite bands at the time.  During the start of the New Year they parted ways with second guitarist Kerry Roberts (Kris Coombs-Roberts's brother) and found a suitable replacement in Darran Smith (ex-Tripcage). The band recorded four tracks at Mighty Atom Studios for a proposed self-financed EP with another Welsh band From This Moment On. Upon hearing the tracks, Mighty Atom Records approached the band and offered a two-album deal, resulting in their debut EP, Between Order and Model (2002). Before the EP's release, Andi Morris (bass) quit, with Phillips and Evans also leaving. The band then recruited Gareth Davies (later Ellis-Davies) on bass and Ryan Richards on drums. Matt Davies became the band's only primary vocalist, with Gareth Davies performing backing melodies and Richards taking over Evans' screaming role.  In 2003, Funeral for a Friend recorded their second EP, Four Ways to Scream Your Name, produced and mixed by Colin Richardson. In mid-2003, the band secured their first Kerrang! award, winning the award for "Best UK Newcomer", beating The Darkness, who won in all other nominated categories. Funeral for a Friend's win was largely attributed to their fervent fan base, as the awards winner was decided by public vote online at the official Kerrang! Web site. In August 2003, Funeral for a Friend opened the Concrete Jungle stage at the Reading and Leeds Festivals.
