Gareth Michael "Gaz" Coombes (born 8 March 1976) is an English musician, best known as the lead vocalist and guitarist of the alternative rock band Supergrass.

His father was a food scientist, who enjoyed playing jazz piano,[1] and his mother was an English teacher.

After the mild success experienced by The Jennifers, but still living with his parents, Coombes got a job at the local Harvester.

With Danny Goffey they began to practice at Quinn's house, and Supergrass was formed shortly thereafter.

The band released six studio albums in their 17 years together, each of them entering the UK top 20: I Should Coco (1995), In It for the Money (1997), Supergrass (1999), Life on Other Planets (2002), Road to Rouen (2005) and Diamond Hoo Ha (2008).

During the height of Supergrass's fame, around 1995, Coombes received offers from Vogue Italia and Calvin Klein to model for them in their ad campaigns and magazine publications,[7][8] as well as an offer from Steven Spielberg to make a Monkees-style TV show of the band.

"[6] Coombes appeared on The Annex on RTÉ 2fm with Jenny Huston alongside Goffey before Supergrass took the stage at Malahide Castle in Dublin, Ireland to support Arctic Monkeys on 16 June 2007.

On 12 April 2010, Coombes and the rest of Supergrass announced that the band was to split after seventeen years.

[19] On 24 June 2016, Coombes supported The Last Shadow Puppets (featuring Arctic Monkeys' front man, Alex Turner, and Miles Kane) at Bristol Summer Series.

He moved to a Regency townhouse in Brighton, East Sussex, which he first purchased in 1999, with his partner Jools Poore and their daughter, Raya May (born 2003).
