My guests this week are the members of The Hermes Experiment, a contemporary music quartet made up of Heloise Werner (soprano and co-director), Oliver Pashley (clarinet), Anne Denholm (harp),  Marianne Schofield (doube bass), and the group's co-director Hanna Grzeskiewicz. Having just releases their second album,*Song*, for Delphian Records, the group tell me about the rewards and challenges of running an ensemble with such an idiosyncratic combination of instruments, and have already notched up over 60 commissions from a wide variety of composers.
