That's like me with Agalloch, I picked up Of Stone, Wind and Pillor because the cover was so fucking cool and beautiful, and now I'm hooked. I picked up BWP (my first Opeth cd) mostly for the cover, I'd heard one or two songs and didnt like them that much, but wanted to give them another chance and by buying a CD I thought I would better motivate myself to give them a fair try.
Both worked out wonderfully
