Question: What are both Quietdrive and Supergrass?
Context: Supergrass were an English rock band, formed in 1993 in Oxford.  The band consisted of brothers Gaz (guitar and lead vocals) and Rob Coombes (keyboards and backing vocals), Mick Quinn (bass and backing vocals) and Danny Goffey (drums and backing vocals). Gareth "Gaz" Michael Coombes (born 8 March 1976 in Oxford) is an English musician and singer-songwriter, best known as the lead vocalist and guitarist of the English alternative rock band Supergrass.  He first entered the music scene aged sixteen as the lead singer of the band The Jennifers which featured Supergrass bandmate Danny Goffey.  Coombes was noticeable for his large sideburns during the 1990s. Cheapskate is a US-only single from Britpop band Supergrass' second album "In It For The Money" that rose to #35 for four weeks on the US Hot Modern Rock Tracks chart.  While being only a 7" promotional single, it has an accompanying music video, that was, for an unknown reason, left off the Supergrass Is 10 DVD. "Moving" is a song by Supergrass, from their eponymous third album, "Supergrass" (1999).  It was also released as a single, reaching #9 in the UK Singles Chart.  It is about the tedium of touring as a band.  It was the last song by Supergrass to reach the UK Top 10. Quietdrive is an alternative rock band based in Hopkins, Minnesota that formed in 2002.  Quietdrive released their debut album "When All That's Left Is You" on May 30, 2006 on Epic Records.  In April 2008, Quietdrive parted with Epic Records and released their album titled "Deliverance" on October 14, 2008 with the Militia Group.  In 2009 they parted with Militia Group and released their independent EP titled "Close Your Eyes" on their own independent record label Sneaker 2 Bombs Records.  Their third full-length album, titled "Quietdrive", debuted on December 14, 2010 and their full-length album, titled "Up or Down", on April 24, 2012.  The band's most recent release was "The Ghost of What You Used to Be", which was released on December 16, 2014. "Kiss of Life" is a song by the band Supergrass.  It was released as a single from the compilation album, "Supergrass is 10".  It was a new song, recorded for the compilation and was released in May 2004, reaching #23 in the UK Singles Chart.  B-side "We Dream of This" was built around "Kiss of Life" played backwards.  CD2 was an Enhanced CD with the video for "Kiss of Life" and "Rob's Guide To Responsible Flying", a small section of footage from the "Supergrass Is 10" documentary (released with the DVD version of the compilation), showing keyboard player Rob Coombes smoking illegally in an aeroplane toilet. Quietdrive EP by Quietdrive was released on August 4, 2004 under Epic Records. "Mary" was the third and final single from the Britpop band Supergrass' eponymous third album.  Released in November 1999, it reached a disappointing #36 on the UK Charts, their lowest charting single for 5 years.  This was also the last Supergrass single to be released on cassette. "Rebel In You" is a song by British rock band Supergrass.  It is the third single from the album "Diamond Hoo Ha", and is the band's final single release.  "Rebel in You" with B-side "Car Crash", was limited to 1500 copies on 7" white vinyl only and released on 30 June 2008 via Supergrass Records (the release date and distribution, however, were delayed past 30 June due to a problem at the record pressing plant).  The single is only available for mail order purchase from the Supergrass Records website, with the first 200 copies ordered being signed by the band themselves.  The single was planned to be distributed by Parlophone, but EMI refused to fund its release, along with any costs for the creation of an accompanying video.  The singles' covers all follow the trend of having a gorilla's hand on them. "Seen the Light" is a song by Supergrass.  It was the third single from their fourth album "Life on Other Planets".  It was the first Supergrass release on DVD and reached #22 in the UK Singles Chart when it was released in January 2003.  The B-Side "The Loner" is a cover version of a Neil Young song.
