Queen II is the second studio album by the British rock band Queen. It was released on 8 March 1974 by EMI Records in the UK and on 9 April 1974 by Elektra Records in the US. It was recorded at Trident Studios and Langham 1 Studios, London, in August 1973 with co-producers Roy Thomas Baker and Robin Geoffrey Cable, and engineered by Mike Stone. It is significant for being the first album to contain many elements of the band's signature sound of multi-layered overdubs, vocal harmonies, and varied musical styles.
