Conway and Colley also officially formed the Hi-n-Dry independent record label and studio, converting Sandman's workspace into a commercial enterprise. The label's roster includes a number of their friends, colleagues and other Boston-area musicians. In 2004, Hi-n-Dry released the Mark Sandman box set "Sandbox", which contained two CDs and a DVD of previously unreleased material spanning Sandman's musical career. The DVD featured clips from early Sandman shows, interviews from the Morphine tours, and various videos from other Sandman solo and group projects, such as Treat Her Right. However, for copyright reasons the box set did not contain any previously released material found in the Morphine catalog, Morphine videos, or promotional material produced by Rykodisc or DreamWorks Records.
