Raised in Moscow, Yelena Eckemoff received extensive training as a classical concert pianist before fleeing the Soviet Union for the US. Twenty years later, she has self-released a slew of jazz ailed classical efforts, most recently Glass Son, a song cycle celebrating the change of season from Winter to Spring. Supported by bassist Arild Andersen and drummer Peter Erskine, the trio’s dynamic is highly interactive. Eckemoff’s restrained romanticism and gracefully unpredictable compositions leave plenty of space for Andersen’s assertive, at times overpowering, bass and Erskine’s remarkably understated drums. Poised on gentle dissonances, the hypnotic music soothes even as it animates.
