Like some of her works on the recent portrait album “Tachitipo,” this one derives momentum from hairpin turns that link together drone-ish states and startling streams of motivic activity.

Rogister’s steering of the music’s violent weather had me loosening my tie, and his finely attuned management of its mess of motivic gestures and granular details was superb.
