At the height of grunge, Morphine sounded like nobody else. The Boston trio built their own strange, seductive musical language from Mark Sandman’s two-string bass and unmistakable baritone, Dana Colley’s saxophone and a stripped-back rhythm section, drawing as much from jazz and blues as rock. They became one of the defining cult bands of the ’90s, but their story came to an abrupt end in 1999, when Sandman suffered a fatal heart attack on stage during a concert in Italy.

More than 25 years later, Cocoon offers an extraordinary final chapter. Its eight songs were recorded during Morphine’s late-’90s sessions before Sandman ultimately shelved the material on the path toward what would become their final album. Rediscovered in the band’s archives decades later, Sandman’s life partner and Morphine estate manager Sabine Hrechdakian and producer Paul Q. Kolderie (Radiohead, Pixies) transferred the original tapes and carefully assembled this unified collection of Morphine songs. Dana Colley returned to add new saxophone parts, and Kolderie then brought new mixes to the table. Rather than a collection of demos or outtakes, Cocoon is a fully realized Morphine album revealing a band still pushing forward that somehow waited nearly three decades to find its way into the world.
