31. Grails -Deep Politics
So I'm not sure how many people on this forum know about this incredible band, but if you don't, you should. At their core, they are basically an instrumental post-rock / post-metal outfit - but the reality of this band is that they are so much more than that. Their masterpiece is still 2007's "Burning Off Impurities", I think, but this album is right up there among their best. This is one of their trippier outings, to be sure. Some of it reminds me of 1970's psychedlic movie soundtrack music. It's just...hard to describe what Grails does in mere words. Suffice to say that if you like trippy, experimental instrumental post-rock, then you owe it to yourself to check this band out. This is one of their better albums. Their whole catalog is good, but it varies quite a bit from one album to the next, so a little exploring is advised if you're going to give them a serious chance.
