Theme: Variation - traces an arc spanning 400 years of composition, beginning with Orlando Gibbons' The Italian Ground ca. 1605, and culminating in Variations on a Fantasia of J.S. Bach (2017), an original work from Rogosin's friend Kevin Morse. The result is an album whose explorative gusto is matched by it's sweeping scope. Theme: Variation - sees Rogosin navigate through hundreds of years of compositional variation with aplomb. The liner notes, found in the accompanying iTunes booklet and written by Rogosin, are an indispensable companion as you listen through the record. Rogosin meticulously explains the variations and technical underpinnings of each track while highlighting important or noteworthy nuggets for the discerning listener to catch. Interspersed with technical explanations are personal asides, offering insights or anecdotes surrounding his relationship with the composition.
