The app has VR options for Cardboard, Firefly, and VR One. The sound quality is great. You can really get a sense for the binaural effect as Bjork walks around "you". However, the technical quality of the video is not very good. The boundaries where video feeds were stitched together to make a 360 are fairly obvious, there were a few glitches in the video playback speed, and the overall image quality makes me think that the filming equipment is outdated or they compressed the video file size too much. That said, I don't recommend anyone but the biggest Björk fans with a VR headset to download this app.
