Since 1989, Peacock has been capturing the essence of the Rosario experience on the albums Island Time, Oceans, Suite Dreams, Destination, Island Life, Traveler, Painting Paradise: In the Garden, Love Letters, Origins, Seaglass, and on the Pianoforte series by Pure & Simple Music. Narada Recording Artist Nancy Rumbel and the Grammy Award winning Seattle Symphony string section (including principal cellist Ray Davis) are featured in collaborations with Peacock on most of his albums.
Recorded both in solo settings and in collaboration with guitarist Gene Nery and pianist Richard Palalay, Peacock's albums show the full breath of his talents with arrangements from solo piano to full orchestra, and in styles from classical to contemporary jazz. Pianoël Volumes 1 & 2, compilations of holiday music, feature Peacock along with Pure & Simple artists Nery, Palalay, Daub and Hemisphere. His popular Pianoforte series showcases solo piano performances of popular requests, including music from Broadway and Film.
