It's jazz as repertory music, not jsut in terms of song selection, but also as soloist.
It's really not that much different than a Classical player being able to perform a recital of a variety of musics. EXCEPT - Jazz was not created to be this, Jazz was created for people to find THEIR voices. That's a major difference imo, and also a deal-breaker as to what I would want to support in any way.
If you want to hear the originals, play records. And if you want to hear live jazz, try to find somebody who's not doing this. Find somebody who is at least trying to play their own way.
I would hope that this Aaron West guy is a fully skilled musician who is doing this gig because, hey, it's a gig, right? And I hope that whatever his real thing is gets some exposure as a result of this visibility.
And what I REALLY hope is that "in the role of" just means that he's going to play the solos in his own way rather than just the original solos by rote.
