The record, titled Aegea, was made by Corgan in 2007, and he admits the music is a significant departure from his usual style.
He says, "As a work, Aegea is experimental in nature, and comes across as more a soundtrack to some lost foreign film than the kind of music I'm usually associated with. Listening back I quite like how Aegea goes along, as it has qualities that are both meditative and alien; but not alienating."
Just 250 vinyl copies of the two-disc album, priced at nearly $60 (£37.50), will be printed initially, and each will be hand-numbered and annotated by the musician.
The album is expected to be released later this year (14).
