Vio7 is a rock group that is venturing in uncharted territories of rock music by using 7-string electric rock violin as a lead instrument, instead of guitar.

The leader of the group Armand Melnbardis, well known for his immaculate playing skills as classical player, is clearly proven that he can challenge any guitar player with his driving rock riffs and soaring solos. His violin playing possesses power and range far beyond the capabilities of a guitar.

Drummer Tracy Shell joined the Minnesota hard rock band Gemini in 1993 touring the Midwest and playing on their heavy and experimental third record The Spiritual Dimensions of Music before opening for original Quiet Riot line-up in 1998.

He left Gemini and Minnesota to become a long-time touring member for the Voice of Melodic Metal: Rob Rock, sharing the stage with such heavy-hitters as Thin Lizzy, Ratt, Dokken, TNT, Dio, UDO, Overkill, Twisted Sister, Jackyl, Skid Row, Axel Rudi Pell, Kamelot, and Savatage at shows throughout the US, Europe and Japan. In September of 2008, Tracy performed with Rob Rock at the annual Prog Power USA Festival in Atlanta Georgia, which was recorded and filmed for a CD and DVD to be released in 2009.

In addition, Tracy performed and recorded with The WTKS Philips Phile radio show-formed band ODDO playing major promotions and festivals in the Central Florida area, opening for bands including Offspring, Puddle of Mudd and Damage Plan. Releasing one CD Never Odd or Even, recorded at J. Stanley Productions Inc. (Matchbox20) produced by Marty Ogden (Motley Crue).
