Yes, we did a double-take when we saw that venue name. It's THE Falls, as in the Kendall mall. No, it doesn't exactly scream rock and roll, but there are a lot of the all-ages set dwelling around there, so why not? Rocking the Simon-franchise shoppers this weekend is the local foursome Dear Dad, Yours Truly. Despite the vaguely Warped Tour-sounding name, this young quartet is actually ripe for the "active rock" radio format, with moody compositions that skillfully traverse the gap between subdued verse and anthemic chorus. With every other late-teen/early-twentysomething outfit trying to play a multihyphenated sub-sub-genre, it's an interesting change of pace to see an under-30 group tackle what can simply be called hard rock.
