This is possibly my favourite rock album of the year.
Baroness are honestly not particularly prog in my book (but they're on PA so I figure I can get away with bringing them up here) but I really enjoy Blue Record. I pay it about the highest compliment I can when I say that it's too short. When its 44 mins have rolled by, you feel unsatisfied and need to play it again. They sound a lot like Mastodon (and are from Georgia too) but Blue Record does not have the "trying-too-hard" vibe that spoiled Crack The Skye for me. Baroness sound relaxed even as they play complex and powerful metal- they've remembered not to get too serious, keeping it loose and fun while still being adventurous.
Though on paper Blue Record might look like a slight album- it hardly reinvents notions of space and time or does something astonishingly amazing we have never heard before- it's been executed so well that it adds up to more than the sum of its parts. There's violent noise, there's unexpected beauty, there are even catchy hooks.
So anyway, just thought I'd plug it in the hopes more would check it out. But just a warning, it's more "arty hard rock" than out and out prog.
