Triana was a Spanish band from the seventies. They mixed progressive rock and flamenco. It was one of my favorite bands when I was a teenager. We didn't listen to anything else at home for a while: my mother loved them.
Jesús de la Rosa was the composer, vocalist, keyboarder and soul of it. Unfortunately he died in 1983 in a traffic accident when he was only 35 and the band broke up.
I still think they were great!
This is one of their best songs: "Abre la puerta"
