Bruno Heinen is a London-based Guildhall graduate who studied classical piano and jazz with the formidable John Taylor, and whose crossover projects have included reworkings of Stockhausen for jazz groups, collaborations with the Palestinian singer Reem Kelani and the talented London samba-singer Emily Saunders. Twinkle Twinkle, for Heinen's Dialogues Trio with bassist Andrea di Biase and drummer Jon Scott, scatters elements of the nursery rhyme throughout this group conversation with guest saxophonist Julian Siegel. Heinen's extended lines impart a Bill Evans lilt to the opening waltz, but sharp contrasts arrive quickly – like the darting staccato of Spin Wins for Siegel's furtively twisting bass clarinet. Misty drifters are laid over arresting hooks and then fall back, while fast piano motifs mark out rhythmic territory for Siegel's tenor to roll and wriggle over. Siegel's melodic resourcefulness is creatively stretched by Heinen's writing, as on the rhapsodic Sylvia's Lament and tiptoeing Night Hue – or in the guttural free-improv territory, by the abstract East and Rising. Heinen sounds like the kind of erudite and curious new arrival destined to make a real difference.
