This month Barcelona will get a dose of Latin rap from the giants of the genre, Calle 13. The Puerto Rican duo will present songs from their latest album released in 2014, Multi-Viral. Producer and vocalist Eduardo Cabra (known as Vistante) and lead vocalist René Pérez Joglar (Residente) are step-brothers and bandmates. Every album features prominent vocals by their half-sister Ileana Cabra Joglar (PG-13). Chart-toppers for years, they have been awarded a record-breaking 19 Latin Grammy awards. The brothers are well-known for their complex lyrics that often incorporate social critique and humour, but they’re equally famous for their hard to categorise, genre-blending sound––incorporating traditional Latin music, rock and now a little Irish pop. Recently, they’ve been critical of their over-indulgence during their early success. Not convinced? In the video of ‘Adentro’ from Multi-Viral, Residente goes as far as smashing up his Maserati with a baseball bat and pushing it off a cliff to make his point.
