You just can't fight the freedom urge. Formed in 2012 to celebrate Barry Altschul's 70th birthday the following year, 3dom Factor's first album concentrated on performing the veteran drummer's compositions. But, numerous tours and gigs later, the trio has developed enough of a rapport to strike out into more uncharted territory and this follow-up, recorded off the back of a week-long tour, is comprised almost entirely of spontaneous improvisations (with the exception of a slithering take on Monk's ‘Ask Me Now’ and a tightly bristling go at Annette Peacock's ‘Miracles’). Yet, in many ways, it's less an exercise in pure sonic experimentation and more one of knitting together various different well-established modes and moods. A loping drone- groove reminiscent of Coltrane's ‘Compassion’ splinters into disjointed jabs and parps, tumbles into raging free-bop and settles on a slinky blues with Jon Irabagon's tenor sliding across the changes. Elsewhere, the saxophonist demonstrates the advanced chops that guarantee him a seat in postmodern pranksters Mostly Other People Do the Killing, with tightly reined peeps and purrs on tenor and strangled whinnies and mewls on sopranino. By the time he picks up a flute in the final stretch, over Joe Fonda's joyful hook and Altschul's tumbling brushes, it's clear just how much fun everyone's having.
