Majority of the music of The Powerpuff Girls cartoon series are showcased in the track compilation entitled Heroes and Villains (see album cover). Included are the opening and ending themes of the original Cartoon Network release, plus original songs performed by various groups, as inspired by the series.
The series ending theme and the song Fight the Power featured in Heroes and Villains are performed by the Scottish band Bis. The members of Bis are vocalist Manda Rin and brothers Sci-Fi Steven and John Disco.
Bis originated from Glasgow, Scotland, formed in 1994 when the members were still attending high school. At first, the group played merely for fun but they later became popular in Europe, largely because of their sound that could be described as “techno-pop”. Bis has released about 16 albums.
