The concert, featuring songs from his new album, Abraçaço, earned five stars from the Times and Guardian, both of which call it a "masterclass," and The Arts Desk. The Times also calls it "a perfect evening," the Guardian "exquisite." The Arts Desk says: "Caetano Veloso gets more extraordinary." Veloso tours the US this fall.
