Exactly a year ago, I blogged about ageing rockers and their propensity to continue touring and recording. This past weekend I experienced two events that provided almost polar opposites as to how musicians will perpetuate their “live” legacy. (Of course, in theory, their recordings will last forever, in physical, digital and streaming formats – as long as the equipment, technology and platforms survive…)

On the one hand, there was the Sun Ra Arkestra, who since their founder’s death in 1993, have continued to play the music of Sun Ra, respecting the sound, format and spirit of the original band formed in the 1950s. Some of the current band members played with Sun Ra himself, so there is a thread of continuity that connects us back to the past. But even as these surviving members depart this world, the music of Sun Ra will live on in concert form through subsequent generations of players. This type of perpetuity is not uncommon among bands of the 60s, 70s and 80s, although in many cases, there is usually at least one original band member performing, or members who overlapped with the band founders. (Some notable exceptions: Soft Machine, who continue performing and recording, but whose remaining original member left nearly 50 years ago; and Faust, who split into at least two separate bands that still tour and record under the same name.)

On the other hand, there was the high-tech concert presentation by the late composer and performer Ryuichi Sakamoto, entitled KAGAMI. This involved the use of AR headsets and a 3D avatar of Sakamoto, captured in sound and vision performing a selection of his music, sat at a grand piano. The audience, initially seated in a circle around the virtual performance area in order to acclimatise to what they were seeing, was invited to move around the avatar, and even peer into the open grand piano. Two things were striking: first, the 360 degree image was very impressive in the level of detail; second, even if someone was standing between the viewer and the avatar zone, the headset still presented the image of Sakamoto sat at the keyboard. The technology not only captures a digital visualisation of the pianist in action, it also replicates the notes he played as well as the tonal expression and the timbres, resonances and acoustics of the physical instrument. While the audio HiFi was superior to the atavistic CGI, the latter will no doubt improve; as will the slightly clunky and heavy headsets – the 50 minute duration is probably the most I could have endured.

Neither format of the above concerts is better or superior to the other. Both are authentic in their own way, and true to the artistry of musicians they celebrate. Of course, if we end up using AI to compose “new” music by Sakamoto, that may undermine that authenticity. But given Sun Ra’s origin story, I wouldn’t be surprised if he started beaming his new works from Saturn.
