Has anybody ever heard of a band called Mephistopheles,who released an album called 'In Frustration I Hear Singing' in 1969.

They are a pretty obscure band,I think.Three of them left and became Jehovah's Witnesses and one of them,Gordon Grant,contributed an article to one of that religion's magazines in which he told the story of how this came about.

The figures on the front cover of the album are strange,distorted representations of the group members.Their name comes from a demon in the Faust legend.
