Anybody who knows anything about Opeth or Mikael Åkerfeldt knows that he's a major record collector and a serious geek when it comes to '70s prog and hard rock. So while we had him in the office two weeks ago, we asked him some questions about his collecting habits, and quizzed him on '70s acts like Pink Floyd, Genesis, Hawkwind, Grand Funk Railroad and many more! We think you'll get a kick out of this video...enjoy!

Opeth's North American tour dates with Mastodon and Ghost continue through May 12. Their latest album, Heritage, is available now in our webstore.
