Gotan Project are to release :: Lunatico :: their first studio album since the seminal La Revancha Del Tango on the 10th April. From what I've heard on the XL site, its sounding fab... Similar but more mature and self-assured.
Definately worth checking out... and if you get the chance to see them live then do what it takes to be there - their live show is phenomenal. I went with the Soos to see them in Edinburgh and they were amazing... the multimedia production is tremendous - in fact, the band spent a good part of the show behind a screen with dancers projected on to it.
