Hoppkorv was the seventh album by the American blues rock band Hot Tuna, and their last studio album recorded for Grunt Records. Unlike previous albums, Hot Tuna relied entirely on an outside producer for this effort, Harry Maslin. In addition to four new original songs by Jorma Kaukonen and one by Nick Buck, the album includes covers of Buddy Holly's "It's So Easy", Muddy Waters' "I Can't Be Satisfied", and Chuck Berry's "Talkin' 'bout You."
