Grammy-winning composer Stephen Hartke is widely recognized as one of the leading voices of his generation whose work has been hailed for both its singularity of voice and the inclusive breadth of its inspiration. This second volume of his collected piano music brings together two very distinctive sonatas: Sonata for Solo Piano (1998) composed for and recorded by Vicki Ray on CRI records, and Sonata for Piano Four-Hands (2014), which was written for the piano duet team of Anna Plonsky and Orion Weiss.
