"Trick of the Light" is a song written by bassist John Entwistle for The Who's eighth studio album, Who Are You.

"[5] It features a guitar-like assault throughout the song, described by Pete Townshend as sounding like "a musical Mack truck"[1] and is actually Entwistle's heavily distorted eight-string Alembic bass.

[4] Billboard described the guitar riff as "furious" and "unrelenting," and also praises drummer Keith Moon's ability to "[sustain] rhythmic tension.

"[6] Cash Box said that the song is "driven by powerful guitar work by Pete Townshend and aggressive drumming from Keith Moon.

"[8] Who biographer John Atkins says the song has a "muscular texture" and is "fully realized" but that it represents an "orthodox heavy rock format" that the band usually shunned.
