I also saw Tyner two years ago. He wasn't awful, but there was nothing new and he wasn't memorable as, say, Sonny Rollins can still be. (Fortunately, Tyner was backed by Eric Gravatt and Charnett Moffatt.) The last time I saw Brubeck a few years back, however, he put on a fantastic show.
I agree Montreal has had a "same old, same old" program to it the past few years.
