In 1976, while still on a roll, the band released a particularly effective new album, which actually comprised unreleased recordings from their first two productions. It proved to be full of catchy tracks and was enhanced by the different light shed on the combo's music by the track Ride On, where Angus Young's guitar is delicate and Bon Scott's voice almost muffled. These were "studio outtakes" whose power many bands would love to match, as tracks like Dirty Deeds Done Dirt Cheap, Big Balls and Problem Child are unstoppable bombs that would immediately become classics of the genre. As a side note, it was not until 1981, and the death of the iconic Bon Scott, that this album finally reached American record stores, and thus the ears of Uncle Sam's kids; five long years during which the rest of the world had been happily headbanging to the electric eruptions of this brotherhood from the other side of the world.
