Call it serendipity or genius, but when four legends of Texas music pooled their talents in December 1989, a new sound was born: the Texas Tornados. The band was new but its members were no strangers to center stage. Freddy Fender was a mega-star with his hits "Wasted Days and Wasted Nights" and "Before the Next Teardrop Falls." Doug Sahm and Augie Meyers formed the The Sir Douglas Quintet in San Antonio in the mid- 60's in a sound that shook up the pop charts with "She's About a Mover." Then there's Flaco Jimenez, who, along with his father and brother used their accordions to invent their own music genre.
