In the Air tonight DRUMS - phil collins on LP

FWIW I am no fan of the gated reverb drum sound - it was one of the steps on the way towards the loudness wars. This was one of the first few songs to use this technique and may have popularized it.

A Wiki link about how they got the drum sound for that recording. It appears that there were two drummers and a drum machine.

The piece states they used a Roland drum machine up until the climax section. A second drum part was added at the behest of Ahmet Ertegun. It's unclear whether it's Collins or another drummer. So I read it that there were three separate drum parts.
