The vast majority of their songs are instrumentals. In Ed Wynne's words, this is because, "I've never really liked vocals. Words always get in the way, make everything too specific. Our music is more about creating moods and giving the listener the chance to get whatever they want out of it. Music is better than singing." Minor exceptions to this would be "Dissolution" off of "Pungent Effulgent" and "Iscense" from the album "Erpland". The band's spare use of vocals came primarily when Jumping John Egan was a member. Occasionally during live gigs, he would write poetry and shout it during the song.
