"For those with discerning tastes in music", the "state-of-the-art acoustics" in this "outstanding" Downtown concert hall make for a "first-class" evening listening to the Dallas Symphony Orchestra (as well as other local organizations); thanks to a "gorgeous" I.M. Pei design, it's also an "awesome architectural experience", so "take a guided tour if you can" and catch a free demonstration of the C.B. Fisk Opus 100 mechanical-action organ.
