Origin of Symmetry is the second studio album by English rock band Muse, released on 18 June 2001 through Taste Media.

"Feeling Good", a cover, was written for Broadway by Anthony Newley and Leslie Bricusse in 1964, and first recorded by Nina Simone for her 1965 album I Put a Spell on You.

[9] After completing the Showbiz tour, Muse recorded "Plug In Baby", "Bliss", "New Born" and "Darkshines" with the producer David Bottrill, forming the "backbone" of Origin of Symmetry.

Roy Wilkinson of Q praised it as an "astonishing record... where extra-terrestrial fascinations meet the classical world's more unhinged impulses", adding that "comparisons with Radiohead that dogged Muse's early career now seem all but obsolete".

[19] Roger Morton of NME called the album a "reinvention of grunge as a neo-classical, high gothic future rock, full of flambéed pianolas and white-knuckle electric camp ...

[27] In a retrospective review, Natalie Shaw of BBC Music wrote that Origin of Symmetry "shows a band with the drive and unfettered ambition to create a standalone marvel which not only awakens the ghosts and clichés from prog's pompous past, but entirely adds its own voice".

[28] The author Amy Britton argued that on Origin of Symmetry Bellamy "progressed [his band]'s sound so much that he earned a new title – this generation's guitar hero," highlighting "Plug In Baby" and "New Born".

[29] In a retrospective review in 2021, the Pitchfork critic Jazz Monroe wrote: "Muse were playing melodrama as teenage realism, an extremely, ridiculously honest noise ... By combining goth vulnerability with sci-fi scale and hard-rock drama, [Origin of Symmetry] captures a paradox of young romance: on one hand, Bellamy sounds wracked with despair, but he proclaims his heartbreak with the glee of an ecstatic preacher.

[32] The new mixes also restore elements that were originally muted or obscured, such as string sections on "Space Dementia", "Citizen Erased" and "Megalomania", and a harpsichord on "Micro Cuts".

[18] All tracks are written by Matthew Bellamy, except "Feeling Good" by Leslie Bricusse and Anthony Newley[33]Personnel adapted from Origin of Symmetry.
