This time around, however, the music doesn't lose any power when the band downshifts; witness "Machines," a hazy, psychedelic wonder that hovers in the atmosphere like a thick cloud of pot smoke.

It’s a startling evolution for a group that proudly emblazoned its 2009 debut with the tagline “xtra compressed for maximum listener fatigue,” but it’s also a wise one; the added space in songs like “Receptor” further highlights the intensity when the band finally lets go on full-throated shredders like “I’m Closing In.” Nervosas and Messrs open the show.
