Invocation is available herefrom American Composers Alliance.
In the early 1980’s, I wrote one concert of original chamber music per year for four years. Invocation for Piano and Percussion was written for Chamber Concert No. 2 which took place on May 18, 1982. The concert featured Cindy Baker, playing violin and harp, William Wanser, percussion, while I played piano and bass. The other works on the program were Scenes and Soliloquies (1982) for harp and double bass, and Midsummer Night for violin, marimba, and piano.
Invocation was meant to portray an imaginary earth rite. The work starts soft and builds to a frenzy and then returns, as if regaining its composure. Stylistically, the concert is transitional with Invocation looking backward to my first chamber music concert and the other two pieces pointing forward to the third.
