Filk music is “the particular and peculiar music of science fiction fans” and that is what Off Centaur offers. This is not spacey electronic stuff; almost all of it is acoustic guitar, maybe some wind instruments, and singers singing of the wonders of intergalactic travel. Many of the artists are also science fiction writers. Cassettes are all they release because the length limitations of vinyl LPs were too restrictive. They also have some other items for sale such as bronze sculptures by Arlin Robins on science fiction themes, posters, songbooks, and a large selection of harp music. They have a couple of interesting sampler tapes to ease neophytes into the field.
