On Monday nights, when most restaurants declare a day of rest, theres one joint in the city thats always slammed. On any given night Agua Verde Cafe is an expedition of sortsduring conventional dining hours (and especially in the summer), youve got to be prepared to wait for a good chunk of time to snag a table. But on Mondays, youve got something to watch and hear while you wait. Correo Aereo, a local duo consisting of the beautiful Madeleine Sosin and partner Abel Rocha, set up shop in the cafe, performing traditional music from Venezuela, Mexico, Argentina, and Peru. Though theyve collaborated with Calexico, appeared on a compilation CD for world-music label Putumayo, and had a song featured in the film The Life of David Gale, when they perform in Agua Verdes intimate dining room, they still feel like our own well-kept secret.
