"Natural Science" is a song by the Canadian rock band Rush. It was released on their 1980 album Permanent Waves, as the final song on it. It is over nine minutes long and is composed of three distinct movements: I) Tide Pools, II) Hyperspace, and III) Permanent Waves.
Guitarist Alex Lifeson said:
Once we had the guitar track down, we stuck a speaker cabinet outside—this was up at the studio in Morin Heights, Quebec—and we recorded the natural echo off the mountains in combination with the sound of splashing water and Geddy's voice. We didn't use any sort of synthetic echo on the water track.[2]
