I almost thought a new sludge band just dropped but there's no way Dan G is into that. 

Saw the MBs on March 6, 1972 at the Salle Pleyel in Paris, France.  I knew nothing about the MBs or their music. Went to the concert with a group of friends and my then girlfriend.  We had center seats around 4-6 rows from the stage. Incredible concert that I still remember 5 decades later.
