Currently listening to Radio Tarifa, on their album Fiebre they have a pretty nice tango called Tangos Del Agujero. Helps warm up my mind and hands to practice tangos...
I also like Tu Camisita De Flores by Duquende, has some interesting changes and it's a bit more challenging...
Again the idea here is just to get the mind and hands warmed up...
So what's your favorite tangos song to warm up to?
