Checking out this Nirvana poster at Bear's Cleveland Rock and Roll page sent me off on a random Google search looking for 'Empire Concert Club' stuff and that's how I came across this audio of Nirvana's performance there. I think I've seen these clips in the past but I didn't listen to them, because I assumed the quality was probably not even worth listening to, but surprisingly, these clips sound really good!
On a semi-related note, Foo Fighters announced a Cleveland show today - they'll be at Quicken Loans Arena on September 20th with Rise Against opening. Tickets go on sale this Friday at 10am. Color me very stoked!
