by Iván AdaimeAfter the success of the 1993 rarities collection Grabaciones Encontradas, Calamaro released the second part of this material just a year later. Like the prior album, these songs were mainly composed between 1984 and 1994; some are studio demos while others are experimental home recordings. The most important track in this album is the version of Pablo Milanés "Años," a historical duo collaboration with Sumo's singer, Luca Prodan. For years this song wasn't available (it was originally included in a greatest-hits compilation in 1987). There are also another covers like José Alfredo Jiménez's "En el Ultimo Trago" and Leon Gieco's "Todos los Caballos Blancos." "Buena Suerte y Hasta Luego," the first single from that album, is actually an outtake from Calamaro's masterpiece, Nadie Sale Vivo de Aquí. Although this is a demo, the song is good enough to stand as one of the singer's unheralded classics. There are plenty of style mixes (candombe, pop, jazz, blues) and much experimentation. It's fun, to be sure, especially for fans.
