Prior to joining Hawkwind, Tree played with 2000DS, Plato's Jacuzzi, Captain Jesus and the Sunray Dream (who released two limited-edition "private press" LPs), and his own band, Bastard. He contributed vocals and bass to Bajina in 2000, with
Dino Ferari (
drums) and
Judge Trev Thoms (lead guitar). Also with Ferari and Thoms, he recorded two new tracks for the Steve Took's Horns album,
Blow It!!!, built around a session of three tracks recorded 29 November 1977 at
Pathway Studios,
London, by Took with Ferari and Thoms; that album was released on 10 August 2004. After these musical excursions he contributed vocals and bass for Thoms (lead guitar and vocals), Jim Hawkman (
synthesizer), and John Morgan (
drums) with the Mother Of All Bands (M.O.A.B.). Since then, amongst other various musical projects, he has played with the Leeds-based band The Sewer Suckers, who supported bands such as My Older Ego in his home town.
Hawklords have annually released an album, namely;
We Are One (2012),
Dream (2013),
Censored (2014),
Re:volution (2015),
Fusion (2016) and
Six (2017); although Tree did not appear on the latter. ==References==
