"If I had been God," sings Roger Waters in "Déjà Vu," "I would've sired many sons, and I would not have suffered the Romans to kill even one."

It's the brand of irreverent philosophy we've come to expect from Waters, best known as one of Pink Floyd's two front men from 1965 to 1985. It's all over his lyrics to The Wall, the iconic, 1979 concept album on which he also sang the role of troubled protagonist "Pink."

When Pink Floyd released The Final Cut, in fact, that 1983 album was credited to "Roger Waters, performed by Pink Floyd." David Gilmour had asked for production to be delayed until he could write new material; Waters said no. That and plenty of other disputes incited Waters' departure from the band plus subsequent legal action to prevent Gilmour et al. from retaining the Pink Floyd name. Ultimately, Waters was unable to wrest the name away, though he did retain most rights to The Wall. In 2013, he admitted he'd been wrong to sue but added, "Of course I was. Who cares?"

Waters struggled to find success as a solo artist, suffering abysmal reviews for his 1984 album The Pros and Cons of Hitch Hiking. He fared little better with Radio K.A.O.S., a 1987 album he himself came to loathe. Thus, it delighted many but surprised few when Waters celebrated the late-1989 fall of the Berlin Wall with an over-the-top stage production, The Wall - Live in Berlin, in July 1990. Hundreds of thousands of fans packed the area between the Brandenburg Gate and Potsdamer Platz as hundreds of millions more watched on TV or listened on the radio. Waters was joined on stage by Bryan Adams, Tim Curry, Thomas Dolby, Cyndi Lauper, Joni Mitchell, Van Morrison, Sinéad O'Connor and the Scorpions - but no other member of Pink Floyd. He reunited with Gilmour and Pink Floyd exactly one time, at a 2005 "Live 8" benefit concert for poverty relief.

His successful In the Flesh and Dark Side of the Moon tours proved Waters appeals most when he offers a mix of Pink Floyd classics with fresher material. That's exactly the cross-generational spectacle he's offering on his 44-city Us + Them tour, which draws only a quarter of its content from his latest album, Is This the Life We Really Want? It's an album that fires pointed criticism at U.S. politicians, especially Donald Trump, while exhorting Western citizens to remember the alleged "other" is seldom our greatest enemy.

"There is no them," Waters explained to the Arizona Republic. "We're all human beings and we have to accept that. Then we can move forward. Otherwise we're gonna blow this f---ing planet up and there won't be anything left for anybody."

Expect psychedelic imagery, flying pigs and an encore that promises to leave 23,000 adoring Pink Floyd fans comfortably numb.
