spent their early years honing their tripped-out psychedelic pop sound, then after proving themselves masters of the form with the 2014 album , decided that every release they did would have some kind of thematic hook or experiment driving its creation and execution. was all done on acoustic instruments; consisted of four ten-minute songs; and the amazing prog-psych epic was touted as the world's first continuously looping album. A band less dedicated to being weird would have packed it in at this point and gone back to cranking out blown-out psych rockers, but these guys are way too dedicated for that. For their 2017 album , decided to investigate microtonal tuning, a non-Western way of tuning that involves intervals smaller than a semitone. They had a custom-made guitar gifted to them, then realized they needed to create other microtonal instruments to match. With a $200 budget each, the bandmembers bought new gear and altered the instruments so they could be tuned in a way that made them compatible. The new tunings don't radically change the band's way of doing things; the songs are still crunchy, twisting jams that have huge hooks and exciting sections of instrumental prowess where they join together in a furious wave of sound that almost feels unstoppable. This time though, the melodies are are more exotic (to ears attuned to Western music anyway) and complex, as the leads are played by the differently tuned guitars, howling Turkish horns, and murky keyboards, giving them a psychedelic twist. The opening "Rattlesnake" sets the scene over seven long minutes of hypnotic guitars and chants, then the following tunes take things to mellower, trance-like places ("Melting"), dole out intense bursts of heavy rock that wouldn't have sounded out of place on ("Open Water"), delve into some East-meets-West balladry ("Billabong Valley"), and make the kind of expansive, perfectly layered psych they've specialized in for years ("Nuclear Fusion," "Anoxia"). As the album concludes, it's clear that the experiment was a success and that the microtuned instruments fit in perfectly with their oddball aesthetic. It's also evident that can do no wrong, and as the first of five planned albums for 2017, will be hard for them to top. It also sends a message to other bands plying a similar trade that they better step up their games if they want to stay close to 's level. ~ Tim Sendra
