=1

=1 is the twenty-third studio album by English rock band Deep Purple, released on 19 July 2024 by earMUSIC/Edel AG.

It is also the band's fifth collaboration with producer Bob Ezrin, who has produced every Deep Purple album since 2013's Now What?!.

Themes and reception
The album has been described as having a loose concept around "[symbolising] the idea that in a world growing ever more complex, everything eventually simplifies down to a single, unified essence. Everything equals one".

Music writer John Aizlewood described singer Ian Gillan's voice as "richer than it’s sounded in years".
