I'll be Barcelona in mid-October and one of the places I want to visit is the Palace of Catalan Music. I'm trying to decide between a daytime English-language tour and an early-evening concert (in the main concert hall). I'm sure I'll get more information on the tour but a concert would be a different way to see the place, plus not cutting into daytime sightseeing elsewhere. The concert is two young pianists, I'm sure they're fine but the music itself isn't that important to me. The prices are comparable so that's not a factor.
Any advice based on anyone's experience? Is the tour really good? Is the experience of hearing a concert there competitive?
