It remains to be seen whether Donald Trump will get the "big, beautiful wall" he's advocated building between the United States and Mexico. But if nothing else, he's given Roger Waters an idea.

Euro News reports that during an appearance with his fellow Pink Floyd co-founder Nick Mason to promote Their Mortal Remains, a multimedia exhibit created to celebrate the 50th anniversary of the band's "Arnold Layne" single, Waters said he was considering a performance of Floyd's classic The Wall at the U.S.-Mexico border.

But before he's willing to entertain the idea seriously, Waters seemed to indicate he'd need to see proof of a substantial groundswell of resistance against the idea of walling off the United States against its southern neighbor. "Before this can happen, there will first need to be an awakening against these far-right policies," he told reporters. "The sewers are engorged by greedy and powerful men as I speak to you."

As fans are no doubt aware, the idea of performing The Wall near an actual wall is nothing new. Waters notably did it in 1990 in Berlin, eight months after the fall of the Berlin Wall, leading an all-star lineup through a performance later commemorated with an album and film. He's since run through the LP live many times over the years, most recently through a lengthy tour later captured in a documentary.

Even if he doesn't stage The Wall again, Waters has no shortage of things to keep him busy this year. Aside from plotting a North American tour, he's readying the release of Is This the Life We Really Want?, his first solo LP in years — and he also recently expressed a willingness to reunite with fellow Floyd survivors Mason and David Gilmour.
