Peter Trewavas (born 15 January 1959)[1] is an English musician, best known as the bassist of the progressive rock band Marillion.

The new project was designed to be a creative outlet for Pete Trewavas (who has traditionally recorded in a "band" or "group" format on bass and acoustic guitar), in which he could also play lead guitar, lead vocals, drum programming and keyboards as well as have full creative control over the writing and producing of the record with.

The 72-minute concept album In The Last Waking Moments... about a man fighting to understand if a recent bizarre happening was reality or a descent into madness, was released on 11.11.11.

The album featured Eric Blackwood on lead vocals and guitar and composition again along with Henry Rogers of DeeExpus and Touchstone.

On 17 September 2012, during a Marillion concert at The Junction in Cambridge, Steve Hogarth announced that Trewavas was now called "Sweet Pea Tremendous" as it was the result of putting his name into an anagram solver.

Primarily a bassist, Trewavas has also been known to write keyboard parts during his time with Transatlantic, and has played acoustic guitar on Marillion songs, particularly "Faith" and "Now She'll Never Know".
