Brazilian singers Gilberto Gil, left, and Caetano Veloso give an interview at a recording studio in Rio de Janeiro, Brazil, Wednesday, May 27, 2015. As close as brothers, the two have helped one another make the most of the limelight since meeting in 1963 in the colonial city of Salvador, coming together periodically to write songs, produce one another’s albums or perform. The two 72-year-olds are continuing that relationship with a joint tour of 10 European countries from June 25 to Aug. 2. (AP Photo/Felipe Dana) less
