Prime musicianship and haunting melodies make excellent bedfellows, especially when mixed with mesmerizing polyrhythms and punishing heaviness. On Intronaut’s latest, drummer Danny Walker proves that he’s perfectly suited for whatever feel is waiting around the next corner. The infectiously jilting riff of “The Welding” is matched by Walker’s broiling snare beat and thick kick sound. The album shows the ample breadth of the band and gives Walker an expansive playground to demonstrate serious chops; marquee moments include the unfolding of the second half of “Eventual” and the jazz feel of “Harmonomicon.” (Century Media)
