Jarcrew

In 2001, they released their first single, "Paris and The New Math" on Complete Control Music (Community Music Wales' record label, the same label that was responsible for the first People in Planes release back when they were known as Robots in the Sky) soon followed by the band's debut album Breakdance Euphoria Kids (a line from track 8 of Breakdance Euphoria Kids, "Money Shot") and the single "Capobaby".

While rumours of a forthcoming reformation persisted, Kelson (along with final Jarcrew bassist, Hywel "Ricardo" Evans) most notably assumed the bass duties in Future of the Left with former mclusky members Andrew 'Falco' Falkous and Jack Egglestone.

Mathias vacated the position in 2010,[1] and assumed the bass duties in Hywel "Ricardo" Evans' group, Truckers of Husk (along with two additional former Jarcrew members, Rich Williams and Rhod Thomas).

In December 2010, Kelson and Hywel appeared on Bethan Elfyn's Radio 1 Introducing show to discuss the band, play a previously unheard demo from the unreleased second album ("Hello Monster"), and hinted at the possibility of a reunion.

A man introduced as "Ricardo" – who, according to Kelson, did not speak a word of English but was "fluent in the language of rock" – was the band's bassist for their appearance at the 2004 Compass Point Festival in Cardiff (this later turned out to be Hywel Evans, who would remain Jarcrew's bass player up until their split in 2005, and later went on to form an instrumental rock band called Truckers of Husk – he was also credited as a songwriter on an early Future of the Left track, entitled "The Fibre Provider").
