(1) UnderScorE : Contemporary Melodic Rock band from Salerno, Italy.
The “UnderScore” came to life in the spring of 2003 when Pasquale (bass and vocals) and Antonio (former guitarist) decided to set up a cover band. The duo were soon joined by Diego (drums) and Carlo (keyboards) and before long, in the summer of 2004, the group gave up cover songs and started to write their own material, coming out with its first demo in 2005. In April 2006 Antonio left the band and after a number of unsuccessful experiences with other guitarists, the band decided to experiment with a new, melodic and distinctive, guitar-free sound. The experiment proved successful and the sound was at once captured and used to great effect on the four-track “Children On Birthday” EP.
