I've been on Team Biffy for quite a while and have all of their albums, including all the b-sides. I've seen them live a couple of times, and they really do live up to the hype. I love their older stuff and the newer, more slickly produced albums alike, but I think that "Opposites" has some of Biffy Clyro's best songs yet. It's wide-ranging, emotional, experimental, thoughtful, and challenging. I don't love all of the songs on the double album, but I love most of them and I like the others very much. In fact, there's not a single one I skip over when I play it, which I can't say about their other albums, as much as I love them. The double album format can sometimes drag on a bit, but in this case it opens up a broader experience - the guys clearly put a lot of thought into which songs would be included, and there's no filler here. You can listen to either CD by itself or even the individual songs by themselves, but taken all together, the songs in their intended order make a cohesive whole that's very satisfying. Be aware that the version that seems to be on sale here is NOT the full double album - six songs are missing. If you are a true fan, you'll want to have all of them, so go to the band's website or iTunes or whatever you need to do to get the deluxe version (which also has a DVD with a lot of fun behind-the-scenes footage of the recording, as well as the guys' own words about what this album means to them). The shorter 1-CD edition is still very good, especially if you are a more casual fan or if "Black Chandelier" is your introduction to the band. It delivers most of the best songs off the double album (notable for their absence are "A Girl and His Cat" and "Little Hospitals") and does not feel incomplete (unless you've heard the full version). You will not be disappointed, but if you really like the short form, do yourself a favor and go for the deluxe version too. Then catch them live next time they come through your neck of the woods. It's money well spent.
