Joseph Gabriel Rheinberger made his name as a celebrated organist and teacher, but he was also a remarkably productive composer across every genre, including a substantial body of piano music. This album traces his piano sonatas from the high-spirited Second through to the Fourth, whose defiant opening gives way to a hymn-like Romance. Grounded in Classical-Romantic tradition, the music is polished and carefully balanced, favouring clarity of structure over virtuosic display. Above all, Rheinberger shows a gift for flowing, memorable melody that keeps these sonatas consistently appealing. Taken together, the set makes a persuasive case for a composer still best known for his organ works.
