I don't know, I think that instrumental solos of any kind are pretty much non-existent in today's pop music. The last time I can think of popular keyboard solos in pop music goes back into the 80s with songs like Toto's Rosanna, Al Jarreau's Mornin, etc. I can't think of a single pop tune from the last 25 years with a keyboard solo. Maybe Bruce Hornsby's first hit but again that was the 80's or early 90's. Maybe a topic for a different thread?
