Such Hawks, Such Hounds explores the music and musicians of the American hard rock underground circa 1970-2007, focusing on the psychedelic and ’70s proto-metal-derived styles that have in recent years formed a rich body of unclassifiable sounds.
This pretty sums up what this film is all about. Some of the bands mentioned or interviewed here are Pentagram, Earthride, The Obsessed, Kyuss, Sleep, Om, High On Fire, and a lot more. I especially enjoyed the part about Sleep, but pretty much all the footage of the movie is awesome. Besides interviews, you get a lot of rare live footage to see, which alone makes this worth watching.
