Our free download this month is a special treat - a song that will occupy a place of honor in your hard drive. Culled from the recently released Ismael Rivera compilation Anthology, "Arrecotín Arrecotán" finds the one-of-a-kind sonero 'Maelo' in the company of the Puerto Rican orchestra led by musical genius Rafael Cortijo. These are the very roots of the music that would later be known all over the world as "salsa." All the elements are in place: the breathless, vocalizing and inventive wordplay, the rock-solid timbales beat, soulful coro and the lush riffs from the jazzy brass section. Enjoy "Arrecotín Arrecotán" - and dance the night away.
