Before this goes South with talking vrs. less talking its called "Entertainment" Whatever works for your audience is good. Victor Borge found out his comedy and talking was more effective then his virtuoso piano technique.
Right now the hottest act around here is A Dueling Piano setup with a guy and girl using medium quality digital pianos in faux baby grand shells and reading Ipads. No great piano chops or vocals, no 5k digital sounds, just talking, jokes, requests and sing alongs.
Entertainment is what sells.
