Salisbury

With their third release (and second album of 1971), Salisbury, Uriah Heep issued their first real ambitious work. While their first couple of albums (Uriah Heep and Look at Yourself) were cut from the same monolithic blues-metal cloth as Led Zeppelin and Black Sabbath, it was with Salisbury that David Byron and co. let their admiration of progressive rock seep in—most notably on the album closing, over 16-minute title track, which featured a 26-piece orchestra. elsewhere on the album, the songs are shorter and more conventional, such as the acoustic ballad "Lady in Black" and the jazzy track "The Park".
