Released in july 1975, Black Sabbath's sixth studio album gained another favourable review from Rolling Stone magazine who stated "Sabotage is not only Black Sabbath's best record since 'Paranoid' it might be their best ever. Even with the usual themes of death, destruction and mental illness running throughout this album, the unleashed frenzy and raw energy they've returned to here comes like a breath of fresh air". The album is evidence that the band still weren't afraid of musical experimentation and as such, is their most varied and complex production of their formative period. With powerful signature tracks such as 'Symptom of the Universe' and 'Hole in the Sky' which became firm fan favourites, 'Sabotage' would reach the top 20 in the uk and also number 28 in the us.
