In 2000 Jason kept very busy, touring and contributing to various projects. He recorded a song for a tribute album, and played backup on Roger Manning and Brian Reitzell's album Logan's Sanctuary.

In 2007 Jason is credited as performing several instruments on Becks release from that year, "The Information". It is also rumored that Jason does some limited touring as part of Beck's band.
