“The Scottish composer Martin Suckling (b.1981) waits till his household is asleep, then starts work. The Tuning (Delphian) explores the hours of darkness, including a nocturne and a lullaby, expertly performed by principal players of Aurora Orchestra, the mezzo soprano Marta Fontanals-Simmons and the pianist Christopher Glynn. The songs of the title work move from a contemplation of death to the quietly lyrical Two Spells for Sleeping. A string quintet, Emily’s Electrical Absence, pays turbulent but tender homage to Schubert and Emily Dickinson, with the poet Frances Leviston speaking her own texts between movements. Suckling’s chamber music, unsettling and stirring, deftly captures night’s hauntings.”
