Nancy (www.myspace.com/lixorama) are a six-piece band hailing from Brazil.

The band's first full-length is the work of exchanged e-mails, late night AIM action, swapping Garage Band vocals, guitar parts, and a couple of transatlantic flights. Months later, they regrouped for good, joined by Dreaduardo, Munha and Fernando for two weeks of staying-up-all-night recording sessions in Brasília, Brazil's modernist capital.

After this, quitting their day jobs was pretty easy.

Nancy's main influence is Arrested Development (the show).
