Dripping faucet leading to a flood; performed by?

Back in 1977-78, I went to an audio store to audition Essence Speakers (I think) and the demo album was an orchestrial electronic peace. It was recorded very well and had great sound stage and depth. One song starts out with the sound of a dripping faucet into a glass, the glass fills up and spills over into the sink, the sink fills up and spills over onto the floor and so on and so on until you have a raging flood. For some reason I have been recollecting this song and can't remember who performed it. I thought it was Rick Wakeman's - Journey to the Center of the Earth but struck out. It is in that genre of music style though.

I believe the song may have taken up one side of the album and it may have been a two or three album set.

Okay you song sleuths, have any guesses?

Thank you for your assistance.
