Thomas Elwin is the tenor soloist in Tippett's The Heart’s Assurance – the most remarkable and fearless setting of poetry by young men who fought and died in WW2. These poems, thrusting sensual desire into a landscape of death, finds response in movement by Bernadette Iglich. Katie Stevenson is the soloist in Britten’s bizarre A Charm of Lullabies, composed on poems by William Blake, Robert Burns, Robert Greene, Thomas Randolph and John Phillip – maybe not the kind of thing to sing you to sleep.
