180 Gram Vinyl. Mastered by Bob Ludwig. Half-speed lacquers cut at Abbey Road Studios. 'Sheer Heart Attack' is the third album by Queen, released in November 1974. It was produced by the band and Roy Thomas Baker. 'Sheer Heart Attack' marries the Led Zeppelin-influenced crunch of their eponymous debut, and the sonic gimmickry and thematic ambition of its follow-up, 'Queen II'. They then hitched the result to their strongest songwriting to date: the single, 'Killer Queen,' actually won an Ivor Novello award, and pointed the way forward to subsequent glories.
