Question: Which American rock band was founded first, Mutemath or SWMRS?

Tremonti is an American heavy metal band founded and fronted by lead vocalist and guitarist Mark Tremonti, best known as the guitarist of the American rock band Creed, and the lead guitarist of American rock band Alter Bridge.  The band also consists of rhythm guitarist Eric Friedman and drummer Garrett Whitlock.  Bassist Wolfgang Van Halen was in the band between 2012 to 2017.  What originally started as a Mark Tremonti solo project evolved into a fully fledged band after the release of the group's first album, "All I Was", in July 2012.  That album featured Tremonti himself playing guitar in addition to lead vocals, and the band was joined by Tremonti's Creed and Alter Bridge bandmate Brian Marshall playing bass on tour until his departure later that year.  He was replaced by Van Halen bassist Wolfgang Van Halen, who contributed to the band's second album, "Cauterize", which was released on June 9, 2015.  The band also has another album, entitled "Dust", in April 2016, serving as a continuation to "Cauterize". <SEP>  They drew on a mix of influences ranging from the Beach Boys to the Ramones to create their own brand of rock.  The band added Travis Neumann in 2009, who later left in 2014 due to creative differences.  The band released a demo and a string of EPs from 2008 to 2010. SWMRS (formerly Emily's Army) is an American punk rock band formed in Oakland, California in 2004 by Cole Becker and Joey Armstrong, with Cole's brother Max joining only a few weeks afterwards.  The band released their first album, "Don't Be a Dick", on June 14, 2011.  The band's second album, "Lost at Seventeen", was released on June 11, 2013.  They added Sebastian Mueller as the bassist 2014.  The band's third studio album, and their first under the name SWMRS after dropping their former name, "Drive North", was released February 12, 2016, via Uncool Records. " Drive North" was later re-released and remastered after the band was signed to record label Fueled By Ramen on October 13, 2016. <SEP> Drive North is the third studio album by the American rock band SWMRS, released on February 16, 2016, through their own label, Uncool Records.  It was re-released through Fueled By Ramen on October 14, 2016 when they added the songs "Palm Trees" and "Lose It" to the record.  It is the band's first studio album and second overall release under the name SWMRS after changing their name in late 2014.  It is the first album to feature bassist Seb Mueller and guitarist Max Becker, who previously played bass.  It is the band's first independent release and is also the band's first studio album not to be produced by drummer Joey Armstrong's father, Billie Joe Armstrong. <SEP>  The group consists of lead vocalist and keyboardist Paul Meany, guitarist Todd Gummerman, and bassist Jonathan Allen, but they often perform on any mixture or variation of these instruments. Mutemath (sometimes styled as MuteMath or MUTEMATH) is an American alternative rock band from New Orleans that formed in 2002.  They draw heavily from influences in 1960s and 1970s soul, psychedelic rock, and jam band styles, utilizing vintage guitars and amplifiers, as well as Rhodes keyboards, synthesizers, and other electronic instruments such as the keytar.
