The online bio for Boston space-rock quartet MOONS reads simply: “A heartfelt story of some metal and hardcore kids that got into Hum, Swervedriver, and Failure.” Rock bios are usually the biggest waste of time this side of plugging band Web sites on stage, but that’s some succinct shit right there. “Jupiter Drive,” the first track off this summer’s Stasis 10-inch, initially hits like those explosive chords in Hum’s “Stars” before settling in to a post-hardcore comet ride, each riff a galactic blast of post-rock force.
