About the work:

First written for piano solo, the composer transcribed the original into mallet percussion and piano. Psathas says: 'Rhythm Spike - as it was originally named - became Spike, for mallet percussion and piano. Taking as its starting point the most primitive of musical ideas, the repetition of a single note, Spike moves through many environments, rising and falling in waves of intensity - some ecstatic, some dark, some effervescent - all the while maintaining this primary impulse, tapping out a one-note rhythm. I once received an e-mail message from a music student who claimed to have deciphered the morse-code messages embedded in the piece.'
