Rui Vargas is the “Guru” of dance music in Portugal. Has been spinning records since 1988, is the Dalai Lama of Lux Frágil, and a kind of Saramago at the national radio, where he weekly tells an impossible story, of love and wisdom. If you can listen, hear. If you can hear, dance. Rui Vargas, Sunday 22nd, at Elétrico.
