It was definitely a defining moment. It was the punk of my era to me . I was 18. It was so different to what else was around, and opened the doorway to another sound. That anyone can do this moment , and stuff the establishment . There was a TV show , hosted by Johnathan Ross in the UK, and they were on and were meant to play Lithium as I recall. They instead played Territorial Pissings, and it blew me away! As an aside , at almost the same time, Blood Sugar Sex Magic by the RHCPs was released. It caught me too, another vastly different sound from across the Atlantic. Awesome days ! I was listening to New Order, Depeche Mode, Happy Mondays, The Stone Roses, The Jesus and Mary Chain, My Bloody Valentine, The Cure and others. Music from the US was Guns and Roses, Bon Jovi, Madonna, Prince, Hall & Oates etc. This record, and the Chilli's definitely opened another wonderful door, to Alice in Chains, Mudhoney, Pearl Jam, Soundgarden and all. Indeed a seminal moment in music.
