Not exactly Queen, but Freddie's 'Overture Piccante' has some stuff playing backwards, I guess to fit the theme of it being a revisit to the other songs on the album?
yes, there are some: parts of the guitar solo on Flick of the Wrist, I guess the last "ssssh" on Death on two legs, and the intro/outro of the ADATR album is also recorded backwards.
And on Lap of the Gods the Rogers cymbals are recorded backwards - they swell and fade away again - it is recorded one time backwards to the first take.
I guess there are more backwards things on the first albums, but it is quite hard to tell without really listening to it!
The whole of the solo on the BBC version of Flick Of The Wrist is backwards.
Also:
- The final 'Headlong's at the end of Headlong.
- Reversed cymbals at the start of Play The Game
- Reversed piano in Another One Bites The Dust
- I think there's some backwards guitars in The Miracle
- There's some backwards synths at the start of Was It All Worth It
- There's a whole backwards bit in the middle of The Fallen Priest
- I think the bell things at the start of The Dark are backwards too
I was listening to ANOBTD the other day and thought some of the cymbols might have been backwards. i think it was around the end of the first verse/chorus. The cymbols just didn't sound "normal". it wasn't a cymbol crash, but a sustained cymbol (not musically technical I'm afraid), but sounded unusual so I thought it might have been backwards
Perhaps some effects in Flash Gordon Soundtrack can be reversed synths or stuff like that.
Also, in the "battle" of Ogre ... Battle, there can be reversed snare rolls or something to that effect, since there are many crazy sounds there (besides Fred's screaming).
I suspect part of the wall of sound in Funny How Love Is can be a loop of maracas (and/or castanets) put backwards and forwards at the same time.
