"Thru These Walls" is a song by the English singer-songwriter Phil Collins, drummer and lead vocalist for the rock band Genesis. It was released as a single in October 1982, being Collins' fourth single. The song is also the seventh track on Collins' second solo studio album, Hello, I Must Be Going!, released in November of the same year (1982). The song is very dark, which follows a vast majority of songs from the album, and is about a man listening through the wall to his neighbours partaking in unseemly sexual activities.
The song has distinct similarities with Collins's debut solo single "In The Air Tonight", featuring similar atmospheric opening chords on a Sequential Circuits Prophet-5 and even utilizing the same drum part several times in the song that Collins made famous on "In The Air Tonight". The song also features one of Collins's attempts at a "Ringo Starr drum part", who is his biggest influence as a drummer.
The song was the first single by Collins that did not reach the Top 20 in the UK, peaking at a poor chart position of 56 in the UK (it was never released as a single in the U.S.). The song gained little airplay on album-oriented rock or adult-contemporary radio formats in the UK; this may have been down to its voyeuristic theme.
