Kra's style is very "light" musically as well as outwardly - clear, sweet, gentle and especially melodic, even if there are some songs which break through this cliché with their harder parts.

Kra`s popularity increased dramatically after the Peace & Smile Tour Final in December of 2005. The band started in August 2001 and they were signed with the PluS label soon after. On May 18, they released their first demo single “Brise”. Around November of that year they signed on with PS Company after they released their “Hard Lolita” demo tape. Their music is a mix of pop, rock and a bit of jazz. They have an alter-ego band called 36481? and released a mini album that contains four cover songs of other PS Company artists in 2004. Kra is already a major band, and debuted with “Heart Balance” on September 21th.

In December 2007, Kra performed at the J-Rock Invasion in Cologne and captivated the European Fans with their very special "Fantasy & Märchen Rock". Furthermore, they successfully released their recent albums "Creatures" and "Escape" here in Europe.
