Led by 90-year-old guitarist and vocalist Don Regelio Martinez, La Sonora Matancera has been called, by the #Guinness Book of World Records, "the group with the longest duration." Formed by Valentin Cane, bassist Pablo "Babu" Vasquez, vocalist Eugene Perez, timbale player Manuel "Jimagua" Sanchez, trumpet player Ismael Goberna, and guitarists Domingo Medina, Jose Manuel Valera, Julio Gobin, and Juan Llopiz Baptist, the band has gone through many personnel changes in more than seven decades. Vocalists in the group have included Daniel Holy, Nelson Pinedo, Albert Beltran, Bobby Hood, Argentine Carlos, and its greatest alumni, Celia Cruz. Original director, Valentin Cane, led the band until poor health forced him to retire at the end of the 1930s.
