Helder has 7 X-Wife concerts.

Formed in 2002, X-Wife set their world-class standard early on: “Rockin’ Rio” (2003), their debut e.p., was a real “stone in the pond”, introducing a band building on a post-punk inheritance from bands like Suicide or Gang of Four, managing to consolidate avast modern lexicon that was already very much their own, where distortion and analogue electronics from a vintage drum machine served an ambitious, well informed song writing style.
