lost souls

Does anyone know if the following lost artists plan to release new albums? These are some of trip hops original groups, meybe because they didn't sell out (morcheeba,moloko), they were overlooked. It's a shame as they produced some great stuff in the mid 90's.
Attica Blues
Andrea Parker
Ingrid Schroeder
Olive/Ruth Ann
Shara Nelson
Nicolette
and Tim Hutton
