The Mavericks used to genre switch a lot..
They would soft rock it with "The Air That I Breathe" (cover of the Hollies) ...Country down with songs like "There Goes My Heart"..or Raul's killer vocals with their cover of "Blue Moon"
To the Spanish side with "Ven Hacia Mi" and Volver Volver.
Rodger Creager Does it to going from Texas country songs like "Things Look Good Around Here" and "Having Fun All Wrong", to Tejano songs like "Celito Lindo" and "Rancho Grande.
