Greyhaven are a phenomenally talented prog band out of Oregan. Their music can best be described as  "Atmospherically Haunting ", with the keyboards the dominant theme. I first heard of them through their 21 minute instrumental demo " Vessel " in 99, 2000 and was taken in from that moment, even though they didn't have the vocals. Yet it gave one an indication to their amazingly unique sound and with the introduction of Brian Francis'  silky vocals the band was complete.
