BWP - band or album title?

"Mikael Akerfeldt: Yeah! I'm a vinyl record collector so I'm on the hunt for obscure stuff. Mostly 60's and 70's stuff. There was this German band called Blackwater Park that released only one album back in 1971. It's super-duper hard to find. I found it myself, paid a fortune for it and it's a good album. It's not like we named our record after them as a homage, we just thought it was a good title. The band itself sounds a lot like Uriah Heep or Deep Purple."

The album is called Dirt Box. It's nothing life-altering but it is a solid album.
