It's a netlabel dedicated to promoting Mexican electronic music. They aim to combine folk mexican sounds, with the tropical bass electronica. Recipe for success.
A couple of weeks ago they even featured a mix by Lisbonite producer/DJ, Roulet: http://www.tropicall.mx/2011/01/05/waya-waya-en-monsta-sounds/
Amongst the artists of their roster is Los Macuanos, a trio made up by Moises Horta, Moises López and Reuben A Torres. Last year at Red Bull Music Academy I met Moisés. These guys have been making amazing spooky tropical beats. Recently I featured on of their tunes on this mix: http://www.circusmaximusmusic.com/2010/12/infestus-presents-circus-maximus-mix.html
Keep an eye on these guys.
