Successful Kickstarter campaign for "Eight O's in Woolloomooloo" premiere, with support from Aaron Copland Fund for Music

The Galax Quartet and Karen Clark successfully completed a Kickstarter campaign to fund the remainder of composer and performance costs of my new work "Eight O's in Woolloomooloo." My heartfelt gratitude to all of you. In these days of commodity culture, it's wonderful to have had your support for hand-made music in the experimentalist tradition of Charles Ives and Henry Brant.

I hope you can join us for the premiere performance on December 4th, at Trinity Chapel, Dana Street, Berkeley, 7:30 PM, followed by a reception at A Musical Offering following the concert. Sponsored in part by the San Francisco Early Music Society. Info here.

Commission from Galax Quartet with Karen Clark


The Galax Quartet has commissioned me to write Eight O's in Woolloomooroo, based on a text by Mark Twain. In this work, Galax will be joined by contralto Karen Clark. Work on the piece is supported by a grant from the Aaron Copland Fund for Music, the San Francisco Early Music Society and the Galax Quartet.

From the first time I heard Galax, a year ago, I was immediately drawn to the subtlety and virtuosity of their playing. The Galax Quartet is modeled after an early version of the string quartet — two Baroque violins, Baroque cello and viola da gamba — developed by the eighteenth century composer and viola da gamba virtuoso, Carl Friedrich Abel. The personnel of Galax include some of the top early music musicians in the world: Elizabeth Blumenstock, David Wilson, Roy Whelden and David Morris.

I first met Karen Clark way back when I was a Visiting Professor at Princeton University. There,as part of the Composer's Ensemble, she gave a stellar performance of my work, Number Man, for the ghost of J.S. Bach for four voices and oboe. I was floored by the flexibility of her voice and by her musicality. I am very much looking forward to collaborating with her and Galax on this new work.
