I can't stop listening to their long goodbye song. I particularly love how they avoid repetition in their sound which is so common in ambient music. There is always some subtle progression that keeps things interesting - it's easy to get carried away on this constant stream of almost naturally evolving music.
Guys - e-mail the band directly to get information and they'll add you to their mailing list. I contacted Sepand to say I enjoyed their album which I downloaded from iTunes. I added their biography to this site, and received e-mails back from the band, and got a free copy of their CD as a thankyou, which was great! Looking forward to their next release!
