X-Wild was a German heavy metal band founded in 1993 by three former band members of Running Wild (thus the name X (Ex) Wild). The trio hired a British vocalist, Frank Knight, and put out their first album, So What!, in 1994.
The band had the support of the majority of fans in Running Wild's fan club but gained an anti-image among diehard Running Wild worshippers becoming notorious as a ripoff band. Even though they used many of the song-writing clichés typical for Running Wild, X-Wild had many other influences and developed a style of their own. Vocalist Frank Knight was often compared to U.D.O.'s frontman Udo Dirkschneider and AC/DC's legendary singer Bon Scott.
X-Wild disbanded in 1997 Rumours say it that one of the band's promoters disappeared with all band's money during the Savageland tour. This resulted in the decay of the band.
