Voltaire’s made a few Star Trek songs before; and one particular Star Wars song that most people should feel ashamed for loving as much as they do (but none are), but only this year did he finally release a full album of Sci-Fi Multitrektual goodness.
His existing songs about the two shows are already there, redone with his full band in the case of most of the Star Trek tracks, along with some new material for both fandoms, crossovers, guest vocals from certain individuals and even a Doctor Who song.
From a Vaudeville look at the classic Red Shirt vs Stormtrooper fight to sexualising Data in a way that is totally safe for radio play, this album is well worth purchasing if you even vaguely like any of the shows on display (and I’d hazard a guess that most people on this forum do like them).
