Bryant fired Amberg and former live show guitarist Ron Marks returned for the recording of "Vanity/Nemesis" in 1990. The most significant change, however, was the return of early bassist Martin Eric Ain, but Celtic Frost's reputation did not fully recover. The group's next (and, as it would turn out, last for several years) album was a collection of rare recordings called "Parched with Thirst Am I and Dying" (1992). The compilation's title was inspired by an old Roman prayer. It featured unreleased material, re-recorded versions of older songs and some studio session versions.
