I'm of Mexican heritage, so I grew up around mostly tejano/nortena music which I've come to reappreciate in later life, even though I once became the laughing stock at a jazz quartet gathering for even mentioning it as an actual style. I've noticed that there's hardly any literature or instruction books out there on this bass style. It usually gets lumped in with COUNTRY bass. And even though both styles have similarities they are so vastly different. There's usually more syncopation, lots of snare and military-style drum rolls accompanying it and it stands out literally from any other style in that the bass is very audible and "in your face"(sort of like reggae) so there's never a problem figuring out the bass line. Perhaps the fact that it's remained a dive bar and dance hall genre is why it's so unappealing to people outside the culture. If anyone knows of any books on this style I'd love to hear from you. Thanks!
