One of the most underrated bands. These guys are the 1970's version of Black Sabbath, but you don't see kids in high school sporting their shirts or talking about them. The recently got back together with their (in my opinion) best vocalist that goes by the stage name Wino.
Above is the song 'Clear Windowpane' from their most popular album 'Born too late' that was released in 1986. I saw them last year playing in San Francisco, they fucking rocked. Check out wiki for more info.
