Harrow & The Bone Meridian are a seven-piece ensemble formed in 2196 around the singular vision of bandleader and multi-instrumentalist Taraa Mehta-Johanssen, who spent her early career playing Circuit dance halls before a Spire patron funded her a studio and a band. The group — including Cian Osei-Ferreira on modular synth, Daria Volkov-Nduka on erhu-electric, Bolade Svensson on tabla-drum augmentation kit, Yuki Marchetti-Okonkwo on bass, and twin vocalists Ro and Sal Figueiredo-Acharya — play what critics have called 'vertical music': compositions that change character entirely depending on which tier you hear them from.

Physical pressings sold in the Circuit emphasize the rhythm section and the vocalists' raw harmonics. Neural-feed versions sold to Tier 4 subscribers contain additional chrome-frequency layers that restructure the entire emotional architecture of each track. Neither version is dishonest — Mehta-Johanssen insists both are complete works that simply address different ears. Their 2209 album 'Weight Distribution' went cross-tier platinum, a rare commercial and critical phenomenon, and they have played the Spire's Aurelius Hall and the Circuit's Furnace Stage in the same week.
