Building Another Wall.

Roger Waters is thinking of doing an outdoor tour in Europe next summer.

Roger Waters, who is down to the last seven shows of his Wall tour, is thinking ahead toward an outdoor leg in Europe next summer. He says, "I’ve become very enamored of the outdoor show. It was a super challenge to see if we could take the arena production and make it work outdoors, and it works beautifully, but it is unbelievably expensive. So we are trying to figure out ways to make the numbers add up to go to Europe late next summer." So far the tour has grossed $333 million.

After this leg ends July 21st in Quebec City, Waters says, he may work on his first studio album since 1992's Amused to Death. "I have written so much... I came up with a song a few weeks ago on the road and then I started playing it a bit with the band in rehearsals. I think it may be the central part and also the kicking-off point for another album. If I don’t work on [an album] later this year, it might disappear, and I might never do anything again. So I think I have to and I’m very enthusiastic about it. And it encompasses a lot of the other songs I’ve written over the years. There are tons of them. I just never found a big enough hook to hang them around."

Waters and The Wall are in New York for shows at Yankee Stadium tonight (Friday) and Saturday.
