Big stage magic shows tend to come and go because it's hard to sustain multi-year runs but Las Vegas has a few long running shows in addition to P&T: David Copperfield (good), Mac King (great), Chris Angel (meh). Piff the Magic Dragon is a more recent show but is hilarious and looks likely to play for years to come. Shin Lim has had a close-up magic show at the Venetian for a few years now and is also great. Plus, there's almost always a few other magicians doing short runs in Vegas at any given time. Just do a search when you're planning to be there.

Elsewhere, Derek DelGaudio's one man, non-traditional magic show In & Of Itself was sold out in New York for over two years and was released as a movie (which is fantastic and on streaming now). However, most large metro areas have live magic shows fairly often, they're just smaller shows in nightclubs, bars, dinner theaters, etc and don't have the budget to advertise. Do a search and you'll probably find something coming up. There's a shocking amount of really good magic happening lately driven by some incredible innovation from new magical inventors (people who create new methods and effects but usually don't perform themselves). And it's global.
