Heckel and Jeckel have a couple of things going for them. First, I’m old enough to remember the rather funny cartoon bearing their name. Second, I really like early Black Sabbath, Big Black, and some of the better stoner rock bands coming down the line these days. These guys do well making something powerful by blending these elements together. I’m impressed.
The link on Heckel and Jeckel’s name leads to Pogo Records’ Bandcamp site. The label releases some creative music. Give them a good exploring.
