You can find downloads of performances by UC Davis’s Empyrean Ensemble here. Composers include Davidovsky, Melinda Wagner, Lee Hyla, Xenakis, Cage, Wayne Peterson, Kurt Rhode and more.
Here are some samples from Eric Moe‘s fine Albany disc that draws upon pieces written for publisher C. F. Peter’s Waltz Project of several decades back, along with some new waltzes. The clip includes music by:
1) Wayne Peterson: Valse Subliminale (2001)
2) (@02:58): Eric Moe: Pulaski Skyway Waltz (2002)
3) (@07:37): Milton Babbitt: Minute Waltz (1977)
4) (@08:51): Virgil Thomson: For a Happy Occasion (1951)
Eric is one of the pianists I am writing for in my consortium project.
