The strange noises produced by Griffiths' piano(contrary to rumours, he does not use a Theremin) are one of the trademarks of Space's sound. Unlike his other bandmates, Griffiths has never performed lead vocals on a Space track, with one exception – "I Am Unlike A Lifeform You've Ever Met", a B-side on the "Avenging Angels" single. However, on the first two Space albums, "Spiders" and "Tin Planet", as well as the B-sides of various singles, he has contributed instrumental tracks, as well as remixes under the moniker Franny Aspirin.
