I'm weird, in that I started with Tangos. Before discovering Flamenco Explained, I had a hard time finding good resources, and just kind of stumbled onto Tangos. It's a strange way to start, but it means one of the first things I did was get very comfortable with rasgueados, which has helped a lot.
After discovering Flamenco Explained, I latched onto Solea, then Alegrias, Sevillanas, Seguirilla, and Guajira- focusing heavily on compas, escobilla and llamadas for each palo, then slowly adding simple falsetas and getting slowly more complicated. Probably 85% of my material has come from Flamenco Explained at this point.
I had just started working on Bulerias when Kai released the Fandangos de Huelva videos... which distracted me away from Bulerias. I'm a little intimidated by Bulerias, and tend to prioritize other palos, from a resource management perspective... (I can lean one Bulerias falstea or compas pattern, or, in the same amount of time, learn two or three for other palos... makes it hard to justify the Bulerias stuff until I have more material for all the others under my belt).
I'm feeling pretty good about my Fandangos, and am excited to jump back into Alegrias to pick up more of the cante and balie accompaniment with the new series on Saturday!
