Bohemian-Moravian Bands by Texas-Czech (Folk Lyric) 1993

I love these Czech-Bavarian bands that landed in Texas of all places. The seminal river for mariachi came from that migration to that part of the United States, bringing the accordion over, just like the drum and fife music of post slavery, they picked up the revolutionary war instruments and played blues on them.
