When Machines Attack is the tenth studio album from the American psychedelic rock trio Circus Devils. The album, which has an abrasive, aggressive sound, was released in 2013, in conjunction with the album My Mind Has Seen the White Trick, which in contrast to When Machines Attack, has a gentler music style. All songs were written and performed by Robert Pollard, Todd Tobias and Tim Tobias.
On behalf of SLUG Magazine, Brian Staker wrote, <blockquote>The track 'WeâÂÂre Going Inside the Head (Of A Winner)' transforms from a somniloquent recitation into an aural assault. A song like âÂÂThe Lamb Gets Even (inst)â recalls early British prog rock in its sound as well as title. The genre is one of Pollard's âÂÂFour Psâ of musical influence (the other three are: punk, pop and psych)âÂÂthey all become convoluted in fascinating ways under the sign of Circus Devils.</blockquote>The Fire Note<nowiki/>'s Christopher Anthony added, <blockquote>The album is full of vocal trickery which gives it a more robotic feel when itâÂÂs paired with the very deliberate sound movements that create the song structures. Looming large drums, chaotic excited vocals and injected sound effects sum up When Machines Attack. It is an engaging record that keeps you at armâÂÂs length as its interesting soundscapes still give you a chill.</blockquote>
