HD Heaven is a live rock/pop set presented at Market Hotel in Brooklyn, with Hannah Diamond leading the bill. Framed as a performance rather than a conventional concert package, it leans on pop structure while pulling at the edges of rock staging and nightclub pacing. In a city where DIY rooms like Market Hotel have long tested new hybrids before they reach larger stages, the show reads as a small-scale marker of that ongoing cycle. The material’s clean surfaces make its underlying tension easier to hear.
