The Mutant Theatre is the ninth studio album by the electronic/trance band Juno Reactor.

Mushroom Magazine gave the album a perfect rating of 10/10, stating, "Juno Reactor’s The Mutant Theatre is truly unlike any other dance album out there, as it’s tied to a unique performance experience like none other.

The album is diverse, every song being its own story but tied together, and it flows exactly as one would expect the live experience to, with high energy beats, soaring vocals, innovative music styling, and a modern but still solidly traditional production quality.

"[2] In a review for We Are Unseen, Richard Spencer wrote, "Viewed purely as dance fodder either for yourself or the flashing bodies on the stage before you, Juno Reactor – the Mutant Theatre ticks all the boxes.

As a listening-only experience, lots of things are done right too, but the fact remains that nothing ever quite matches the pinnacles reached by the excellent twists and turns of the first track, and everything is generally a little overlong if you’re not in a purely shape-throwing mood.
