Sheer Heart Attack', Roger Taylor's favourite Queen album, was released in 1974 and reached Number 2 in the UK. Prior to this Queen were mostly considered a heavy rock band, but this album experimented with a variety of musical genres, including music hall, heavy metal, ballads and ragtime.

At this point Queen started to move away from the progressive tendencies of their first two releases into a more radio-friendly, song-orientated style, illustrated by 'Killer Queen', which was their biggest hit at that point reaching No 2 in the UK. It also went to No 12 in the US Billboard Charts, the first of many hits there. A song about a high-class call girl, it contains the guitar solo that Brian May is most proud of and won Freddie his first Ivor Novello Award. Re-mastered deluxe 2 disc set featuring new bonus content.
