El Montañes (tanguillo). Composed & performed by Pedro Javier González with percussionist Paquito González.
You may remember from a previous post that the tanguillo is a style of flamenco based on popular choral music sung in Cádiz's annual Carnaval festival. Originally the difference between the flamenco tanguillo & the Carnaval version was just the key -- the choral versions were in major or minor keys and the flamenco version was in a modal key (e.g., Spanish Phrygian). Nowadays, the flamenco tanguillo is characterized mostly by virtuosity and harmonic complexity (rather than by key center) in both instrumental and vocal performances.
