I just have found this news (announced yesterday) on FB page of swedish gterma label run by Johan Rehn, who is responsible for many wonderful releases on his label since 2011.
[gterma043] : Sean Washburn - Wave Mantra
We step into the year of 2015 with a retrospective look on an album that has since become quite scarce in the marketplace. Wave Mantra was originally released by Sean himself on this very day, fifteen years ago. It is best described as a sonic journey through an enigmatic and absorbing soundworld with a very rich organic flavour. A beautiful tale that we are very happy to see back in print again. This reissue has, like so many other gterma titles, also been gently remastered by Anders Peterson.
1. To Thee Homage
2. Hemlock Grotto
4. Trans-World India
6. Inner Gate
7. Low Barometer
8. Between The Heartbeats
9. A Sacred Voice - Cloud Tree
