The records keep on tumbling - Roger Waters has now added an astonishing NINTH show, being held on March 20th 2012, at the River Plate in Buenos Aires, Argentina as part of The Wall Live tour. Will his run there at the venue go into double figures? Only time will tell! The RogerWaters.com presale has just begun for those who have registered there with the city amongst their favourites, and the general sale of tickets will go on sale very shortly, through livepass.com.ar.
