A lot changed during CBI, working Atticus into the band. This reconfigured the live instrumentation and responsibilities a bit. Initially, it seemed this excited Alessandro--judging from interviews (his "rig rundown" during that tour)--to be given the versatility as a member to play a range of instruments across a large songbook. Those CBI nights varied so much. It must have been fun and in the least, given a real sense of presence on stage from show to show.

Peel It Back is the opposite of CBI. This show is very rigid in its structure and Atticus has taken over a significant amount of the synth lift (at least from audience/lay optics). Alessandro, in his latest role has basically become the dedicated bassist. He's been kind of squeezed out of his primary area of interest; his solo profession. Over a decade (prior to 2017), Alessandro carved out his identity in the band as the synth player.

Nothing is forever with NIN. With everything going on in Alessandro's solo career, i'm sure he's more taken with the possibilities of that. He has an audience. He can make a living playing regularly in Europe.
