Jon Anderson says that Trevor Rabin has written a piano concerto for Chinese classical pianist Lang Lang http://t.co/SZrIZlkiu3

If this is true (I suppose there's no reason it's not, save that Jon sometimes states things in a way which turns out to be rather different from what they actually are, bless him) it's a great thing to consider that Trevor may also be moving into a phase of his career where he is actively composing long-form classical works apart from his film scoring. And Lang Lang is no stranger to collaborations with rock musicians, having appeared with Metallica to perform their song "One" at the 2014 Grammy Awards.
Hopefully further updates will be made available...the link to the interview is in Henry's tweet, and Jon's comment regarding Trevor's piece comes around the 22:15 mark in the recording.
