I first heard this one in concert and it was presented as “heavy metal a capella.” In concert, it really came across that way. It wasn’t released on album until 1993′s Shut Up And Sing, about five years after I heard them perform it.
When I saw them in concert, the four “classic” Bobs had been joined by Joe “Bob” Finetti, who has performed vocal percussion with Bobby McPheron. Its important to note that every sound on this album is made by a human voice – usually Finetti.
Anyhow, that’s my trip through The Bobs’ work. I don’t have a whole lot of a capella work in my library, so The Bobs will have to represent the genre.
