Swedish progg should not be confused with "prog" as in progressive rock music. Progg was the musical movement from the late '60s/early '70s that was influenced by Sweden's political climate of the era, to some extent by the hippie subculture and in many cases also Nordic folk music. Originally released in 2017, Blod's 'Leendet Fran Helvetet' sounds pretty much like a lost progg classic from the old days. Now the album sees a reissue on vinyl, pressed in an edition of 500 copies and including an insert.
