The bass trombone has a wonderfully rich tone and sonorous depth yet is rarely featured as a solo instrument. The four remarkable works on this disc, all but one composed for Yves Bauer, bass trombone soloist of the Lille National Orchestra, explore the instrument’s technical and expressive range. Vertiges is a concerto in the form of a theme and variations with an array of dizzyingly contrasting moods. Etoile des profondeurs takes inspiration from jazz and popular music. The title Deux Marches d’écart is a pun on the composer’s name (Marc Steckar), while the thrilling Concerto for Bass Trombone and Wind Ensemble is by turns playful, lyrical and heroically virtuosic.
