Well, it did take me four years to even get a digital copy of the album. The thing is, the band made a declaration in which they banned the use and advertisement of their music pretty much everywhere and only worked with small, local record labels.
Tuvalu used to have their music on Spotify (that's where I found them) but withdrew from the site in 2012. Two of their earlier albums had been downloadable on Last.fm until this year.
