Stratus is the stunning new quartet album from violinist Zach Brock and pianist Phil Markowitz, joined by Finnish jazz standouts Jaska Lukkarinen and Ville Herrala. Recorded in the peaceful setting of Sipoo, Finland, the album blends lyrical improvisation, intricate composition, and intuitive interplay into a cohesive, deeply expressive whole. From lush ballads to dynamic rhythmic journeys, Stratus showcases the quartet's chamber-like sensitivity and jazz-rooted spontaneity. Brock and Markowitz, building on their earlier collaboration Perpetuity, offer a seamless musical conversation elevated by a rhythm section that listens and leads in equal measure. A rich, genre-blurring project, Stratus is both intimate and expansive an exploration of sound grounded in trust, nuance, and shared vision.
