These are all great to listen to as well! A synth metal band called The Mantle released a great instrumental album in 2017. Kenny Gs son shreds on the guitar. I like Satriani to relax to for something upbeat, or even some Jaco Pastorias to mix it up. Lots of good stuff mentioned in this thread!Cool! I've been finding other ones too....
And this isn't a new one, I neglected to mention them earlier.... Carpenter Brut.
