It seemed just like old times—sort of. When I last saw the Cure play live, in the summer of ’92 at the Coliseum, the veteran British alt-rock band started with "Open" and ended with "A Forest", which is precisely what it did on Monday night. In between, the group played all of its best-known songs, a smattering of new tunes, and, for the benefit of those who obsess over such things, even a few semi-obscurities.
