snip from CD sleeve

"The songs on this CD were recorded in March 1987 and were included on what has come to be known by diehard Pixies fans as "The Purple Tape". From this collection of 17 songs, 8 were chosen to comprise their 1st album "Come on Pilgrim". These are the 9 remaining songs and feature the original recording of "Here comes your man" as well as a previously unreleased track "Rock A My Soul."

I own every piece of recorded material by the Pixies including all singles and none of these versions are on them.

I WISH there was newly recorded material!
