Anathema. A very good band from the UK. You can read their history in the linked Wiki page.
I'll be seeing them again, this weekend. Met them a few times. Really nice, grounded people. They're gaining a large fan base and rightly so. Below, is one of my favourite tunes from them. It was actually, the first song of theirs I ever heard. Then, I met group member, Danny Cavanagh, who plugged me into his ipod and made me listen to their (then) latest offering!
I never looked back!https://www.youtube.com/watch?v=gbnGT_4sWJM
