Sleep’s Hempispheres completes its release cycle today, 30 October, as the album arrives on vinyl and CD after its digital debut in September. It is the band’s first full-length in eight years, but the more important change is inside the lineup: bassist and songwriter Al Cisneros is now joined by drummer Dale Crover and guitarist Bubba Dupree.
That configuration makes Hempispheres less a routine comeback than a test of what remains essential when a group with such a recognisable sound changes shape. Sleep are still built around weight, repetition and slow-moving riffs, yet the new players bring a different sense of motion. Crover’s history with Melvins and Redd Kross gives the rhythm section an unusually elastic backbone, while Dupree’s background in Void adds a sharper, punk-adjacent edge without reducing the music to speed.
Five tracks, one continuous journey
The album is concise by Sleep standards: five pieces form a sequence that opens with “Have Spacesuit Will Travel” and moves through “The Morrisist” and the title track before the long-form “Arrival of the Industry Ships.” “Whole Wheat Mountain / Well Baked” closes the record. The titles keep the band’s familiar cosmic language, but the material is presented as a new mission rather than an attempt to recreate 2018’s The Sciences.
The record was developed from demos Cisneros wanted to turn into finished songs. Crover entered the process first, and Dupree followed after being recommended for guitar. The sessions took place at the Melvins’ studio with longtime engineer Toshi Kasai. The resulting lineup does not imitate former guitarist Matt Pike’s approach; it works from the same heavy vocabulary while leaving room for new accents.
A physical release that matters
For a band whose music depends on tone, patience and physical impact, today’s vinyl and CD release is more than a merchandising milestone. Hempispheres benefits from uninterrupted listening: riffs accumulate meaning, transitions feel architectural, and the rhythm section’s small changes become clearer over time. The format encourages the attention this music asks for.
The release also lands alongside Sleep’s current touring activity and a comic-book project written by Cisneros. Together they extend the band’s long-running science-fiction mythology without turning the album into a nostalgia exercise. The imagery may be familiar, but the personnel and the musical decisions point forward.
Hempispheres is available digitally and in physical editions. The official five-track sequence and release information are published by Sleep and Third Man Records.
