On the Saturday night of Glastonbury 2023, a dozen DJs bundled into a shipping container in a corner of late-night dance area Shangri-La to share an epic four-hour set. Only those who wandered through one of the tube carriages flanking venue Platform 23 could access the unadvertised event. The legion of artists was gathered by Keep Hush, once a music, streetwear and art blog that’s grown into a community-driven group dedicated to spotlighting rising talent in the UK underground.
