cello rock 

Cello rock is a genre of music characterized by the use of cellos and other stringed instruments such as violin and viola to create a sound, beat, and texture similar to that of familiar rock music, but distinctly reshaped by the unique timbres and more traditional genres of the cello (in particular) and other stringed instruments used. The cellos and other stringed instruments are often electronically amplified and/or electronically modified. They are often combined with other elements typical of rock music such as rock-style vocals and rock-style drumming.
