Close on the heels of Argentina’s Mercedes Sosa, whose soaring vocals brought a D.C. audience to its feet two weeks ago, comes another fabled singer whose work lies at the intersection of art and politics. Joan Manuel Serrat—who recently attracted a crowd of 300,000 to a Buenos Aires concert so emotion-packed it was widely described as “almost like going to church”—is a Spanish writer/singer best known in this country for his protest ballads. But he also celebrates love and poetry in an expressive, edgy voice that ranges from a seductive whisper to a fervent cry. Called by some a Spanish Jacques Brel, he is actively revered in Spanish-speaking countries. At 8 p.m. at George Washington University’s Lisner Auditorium, 730 21st St. NW. $30-45. (202) 994-6800.
