I discovered Jamendo on a whim, finding their app on my iphone. After signing up, then doing some searching and cross-referencing, I discovered Psychocean. This album made me a Jamendo addict.
I figured, if there's other albums out there on this site that are this good, then I need to keep searching. Honestly, I've yet to find an album as good as "Luminescence" on Jamendo. This album is rock solid, start to finish. It's creative progressive rock, reminiscent of Tool, and the heavier moments of Demians or Oceansize. Lots of odd time signatures (5/4 and 7/4, in particular), and the melodic movements are catchy.
My wife has even commented on how much she likes this CD, and she typically doesn't like progressive music. So I believe that this album will certainly have crossover appeal to hard rock and metal fans, as well, so long as the length of the songs isn't an obstacle. Being a Yes and Dream Theater fan, long songs don't bother me, though I can see where they might inhibit the casual listener from enjoying it. And they'd be missing out. Be happy you've stumbled upon this record!
