Carson Cooman is an American composer born in 1982 with a catalogue of works in many forms, ranging from solo instrumental pieces to operas, and from orchestral works to hymn tunes. His music has been performed on all six inhabited continents and has appeared on over 25 recordings. As a concert organist, he specialises exclusively in the performance of new music and over 130 new works have been written for him by composers from around the world. he is also a writer on musical subjects, producing articles and reviews, and serves as an active consultant on music business matters to composers and performing organizations. The centrepiece of this triptych of related works by Cooman is the significant and rich Fourth Symphony, for orchestra and two harps (one of which is tuned down a quarter tone). Its mood fits the title, ‘Liminal’ meaning ‘on the edge of major change’, which is how our world feels most of the time. As with all of Cooman’s work, these pieces are totally accessible, not avant-garde, but explore many modern techniques to produce such effective expression of ideas. The opening piece is Shoreline Rune (for string orchestra and harp) and the CD ends with Prism, a solo organ work played here by Erik Simmons. The excellent Slovak National Symphony Orchestra is conducted by Kirk Trevor.
