Queen‘s fourth record, A Night at the Opera, was a go-for-broke rock moment, the most expensive album ever recorded at the time, a theatrical sojourn in the name of rock and unconventional pop.

Silver-throated Freddie Mercury and the rest of their fab four-esque creative songwriting force pulled it off, topping UK charts for four non-consecutive weeks surrounding the Christmas of 1975.
