They are two of the hottest touring acts around, and both are coming to the TD Garden this week. But that's about all Roger Waters and Katy Perry have in common.

Waters performed Wednes- day night and returns tonight. Perry will be there Friday and Saturday nights.

Here's an entirely too brief preview of both shows. It's hard to imagine that anyone reading this will be at both shows, so just pick the show that interests you and read on!

The 74-year-old Waters, of course, is one of the co-founders of Pink Floyd, though his acrimo nious departure from the band is well documented. (He left in 1985 and began a legal dispute with the remaining band members over their use of the band's name and material.

They settled out of court in 1987, but 18 years passed before he performed with them again at Live 8 in 2015.)

It's amazing that for a guy who hasn't performed with the group that made him famous in essentially 32 years (Live 8 was a one-off), Waters remains one of the biggest acts on the live concert scene. Don't believe me? He's averaging 97 percent of available tickets sold in 2017, according to Pollstar, grossing at least $1 million for each show they have on record.

Why? Well, he plays a ton of Pink Floyd material, and since David Gilmour has shown little interest in either touring with Pink Floyd or doing a massive tour of his own, it's the only place to hear Pink Floyd songs live in an arena.


Without going through an entire setlist, suffice to say Waters plays "Welcome to the Machine," "Wish You Were Here," "Another Brick in the Hall," "Money," "Us and Them," "Brain Damage/Eclipse," "Mother" and "Comfortably Numb," among many others.

Katy Perry is one of the biggest acts in pop music. She has been part of the Forbes list of top-earning women in music from 2011 to 2016 (she was third in 2011, fifth in 2012, seventh in 2013, fifth in 2014, first in 2015 and sixth in 2016), has an estimated worth of $125 million, and has sold more than 100 million records worldwide.

Based on a setlist from the tour opener last week in Montreal, Perry is, of course, playing her biggest hits, including "Teenage Dream," "I Kissed a Girl," "Part of Me," "Roar" and "Firework."

These are the last New England shows on the docket for Waters and Perry, so if you like either of them, make sure to check them out!
