I've been to this venue twice now, both times for concerts of the Boston Philharmonic. I've also been to Symphony Hall and Jordan Hall. Don't get me wrong, this is still a great theater, but it is my least favorite of the three... especially in the summer.
No, nothing to do with A/C, but to do with the seating! The benches they have can be terrifically uncomfortable for long-term sitting (you know, like the kind you do at the orchestra. The cushions are cushiony enough, no compaints there... it is the backs of these things that get quite fidgety! I don't really know how to describe them other than to say: they aren't really flat.
What does this have to do with winter? Well, when it's cold you have have a puffy jacket to serve as a makeshift pillow of sorts.
Now that this needlessly long rant is over...
I like how the seating is in a semicircle around the stage. What I like about this is your head won't be turned 70° for the entirety of the show.
While if you are sitting at one of the ends (on the second floor, at least) you won't see the whole stage... this is typical of halls like this. Also, since The Blue Man Group does not perform here, it is not as important.
Acoustically, since I am not an audiophile I can't comment in much detail. However, the hall being semi-circular and smaller gives the sound a little more "oomph" than a larger hall.
Architecture is pleasant. It is not quite as extravagant as an Opera theater, but not a nondescript space by any means. Enough to get you looking around a bit before the show. Also, the deep wood tones add that "establishment" feeling that help you feel the age and institution of Harvard, and all that preceded whatever performance or lecture you have come to see.
I was also a fan of the large room (hall?) that is the lobby. A great place to do a little mingling and walking about after the show or during an intermission.
A few concluding notes:
* While there is an elevator to the washrooms, I don't think the balcony levels are accessible.
* Bathroom situation is not great. They are kept clean, certainly. Only there can be lines, especially lengthy for the ladies'. read more
