Gem Archer

Colin Murray "Gem" Archer ( GEHM; born 7 December 1966) is an English guitarist, singer and songwriter. He is best known as a member of the rock band Oasis, where he plays rhythm and lead guitar. He has also been a member of the Oasis-associated bands, Beady Eye and Noel Gallagher's High Flying Birds. Prior to joining Oasis, Archer fronted the alternative rock band Heavy Stereo between 1993 and 1999, releasing one studio album, Déjà Voodoo (1996), on Creation Records.

Archer joined Oasis in September 1999, following the departure of founding guitarist Paul "Bonehead" Arthurs, and was a member of the band for ten years until the band's break-up in 2009. Archer contributed to the band's final three albums – Heathen Chemistry (2002), Don't Believe the Truth (2005) and Dig Out Your Soul (2008) – often contributing to the songwriting process and receiving sole songwriting credits on several songs.

Following Oasis's break-up in August 2009, Archer, frontman Liam Gallagher, bass guitarist Andy Bell and drummer Chris Sharrock continued writing and recording together under the name Beady Eye, releasing two studio albums – Different Gear, Still Speeding (2011) and BE (2013) – before disbanding in October 2014. In 2017, Archer joined Noel Gallagher's High Flying Birds as lead guitarist, reuniting him with Oasis member Noel Gallagher, and making him and Sharrock the only members of Oasis to have been part of both Liam and Noel Gallagher's post-Oasis projects. In 2024, after a fifteen-year break from the band, Archer rejoined Oasis ahead of their Oasis Live '25 Tour. In 2026, he was inducted into the Rock and Roll Hall of Fame as a member of Oasis.
