Deep Purple is raiding its vaults once again, this time going back to its Mk III lineup. 

"Graz 1975," the latest release from the Official Deep Purple (Overseas) Live Series, comes out September 23 on CD, vinyl and digital download, capturing an April 3, 1975 performance at the Liebenauer ice rink in Graz, Austria during the tour supporting the group's "Stormbringer" album. 

It's also the first of guitarist Ritchie Blackmore's last three shows with the band before quitting for the first time. 

The tracklist includes: "Burn," "Stormbringer," "The Gypsy," "Lady Double Dealer," "Mistreated," "Smoke on the Water," "You Fool No One" and "Space Truckin'." 

Here's a video of Highway Star recorded that same year:
