Oh, sorry about that. I did check before I posted the link but when I got the "download as" dialogue I assumed it was okay. My bad.
They must have removed the wav file. Still, the mp3 is 256k and probably good enough to get a good feel for the band/track, which is a real Epic.
If you like it they have it here

as flac for a mere £1 or just £4 for the entire album. That album is staggeringly good and a real "gateway" to the band. imho £4 is an absolute steal (steel?) for it!
