Sound & Vision has long been an advocate for surround sound music. Back in the SACD and DVD-Audio disc heyday, we regularly reviewed multichannel music releases in those formats, and when they eventually ground to a halt, we moved on to music-only Blu-ray audio discs and then Deluxe Edition box sets. The latter now serves as the most common outlet for surround music on disc, most often presented on Blu-ray in the immersive Dolby Atmos sound format.
