For those unfamiliar with the work of Canadian virtuoso bassist Antoine Fafard, this collaboration with Gavin Harrison is a fabulous place to start. Six tracks are with a core quartet comprising Harrison and Fafard with Maria Grig on violin and Jonathan Gerstner on cello. Transmutation Circle has an appropriate measure of drama and showmanship, with Fafard’s improbable bass solos and the dizzying complexity of Harrison’s fills. Elsewhere, guest Jerry Goodman makes the sound only he can on violin on Singular Quartz, underlining the influence Mahavishnu Orchestra had on progressive rock. Yet nothing here is overdone.
