I've heard this album described as heavy metal shredding done on two acoustic guitars. It's not. Half flamenco, half Jazz this album of acoustic guitar tracks is an interesting listen. Why it has such mainstream buzz, I don't know. To me that just brands this as novelty music.
Don't get me wrong, these guys are super talented and this album really appeals to the prog fan in me. I just think that things I can sing along to in the car make for better music.
Amazon relentlessly recomended this album to me, and I kept seeing it pop up on "Best of" blogs, but it wasn't until Amazon made it available for two bucks that I was finally behooved to buy it. It's definitely worth a listen and probably is one of the better albums to come out of 2009.
