Viza is an international rock band with explosive energy and music, containing several influences from all over the world. Unique in its musical arsenal is the inclusion of oud and percussion blended with more conventional rock elements such as guitar, bass and drums. Given the band's members and their respective backgrounds, certain influences and musical strains from Armenian and Greek styles are discernible, fused with elements of modern aggressive rock and traditional music. The band sometimes blends these various flavors with dance and satirical social commentary.

Viza has performed at Hungary's Sziget Festival (alongside Korn, The Killers, Axwell, The Vaccines, The XX), Greece’s Rockwave Festival (alongside The Prodigy, Gogol Bordello, Flogging Molly), Sweden's Malmofestivalen, Norway’s Kartfestivalen, and Slovenia's Schengenfest and Trnfest festivals, among dozens of headline shows, as a part of 6 European tours over the past 2 years.

In August 2010, Viza embarked on a series of introductory performances in Europe, opening for System of a Down frontman Serj Tankian’s “Imperfect Harmonies” Tour in the cities of Yerevan, Athens, Hamburg, Cologne, Paris, Zurich and Bologna. Just this past year, Viza accompanied Tankian again during his "Harakiri" World Tour in the Fall of 2012 as the main support act for 19 shows throughout North America and Europe.

In December of 2011 the band released their fourth full-length album, "Carnivalia", and released the title track as a single. And in July of 2012 the band recorded and released their third single, a cover of "Alabama Song (Whiskey Bar)".

Viza also engages in fundraising for human rights related charities, homeless shelters and orphanages.
