There are multiple projects under the name "T.S.R."

1) T.S.R. is a collaboration between Carbon Based Lifeforms and Solar Fields to write the music for the Swedish dancer Olof Persson's performance "Fusion".

2) T.S.R is a vancouver based folk band formed in 2010 by Steve Bradley and Benjamin Czegeny. After writing and performing a few songs they were later joined by Brett Dennison and Jordan Grant forming an entirely new Band. They have been writing songs since late 2011 and have performed around downtown Vancouver ever trying to evolve and define their sound.
