Cello rock and cello metal are subgenres of rock music and heavy metal characterized by the use of cellos (as well as other bowed string instruments such as the violin and viola) as primary instruments, alongside or in place of more traditional rock instruments such as electric guitars, electric bass guitar, and drum set.

Cellos, often in groups of three or more, are used to create a sound, rhythm, 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 string instruments used. The cellos and other stringed instruments are often amplified and/or modified electronically, and often played in a manner imitative of the sound of electric guitars. They are often combined with other elements typical of rock music such as rock-style vocals and drumming.^{[citation needed]}

Current prominent bands include:

James Marshall "Jimi" Hendrix (born Johnny Allen Hendrix; November 27, 1942 – September 18, 1970) was an American musician and singer-songwriter. He is widely considered to be the greatest electric guitarist in music history, and one of the most influential musicians of his era despite mainstream exposure limited to just three years. After initial success in Europe with his group The Jimi Hendrix Experience, he achieved fame in the United States following his 1967 performance at the Monterey Pop Festival. Later, he headlined the iconic 1969 Woodstock Festival and the 1970 Isle of Wight Festival. He often favored raw overdriven amplifiers with high gain and treble and helped develop the previously undesirable technique of guitar amplifier feedback.

Hendrix helped to popularize use of the wah-wah pedal in mainstream rock, which he often used to deliver tonal exaggerations in his solos, particularly with high bends, complex guitar playing, and use of legato. As a record producer, he also broke new ground in using the recording studio as an extension of his musical ideas. He was one of the first to experiment with stereophonic phasing effects for rock recording.^{[citation needed]} He was influenced by blues artists such as B.B. King, Muddy Waters, Howlin' Wolf, Albert King and Elmore James,rhythm and blues and soul guitarists Curtis Mayfield and Steve Cropper, and the jazz guitarist Wes Montgomery. Hendrix began dressing and wearing a moustache like Little Richard when he performed and recorded in his band from March 1, 1964 through to the spring of 1965. In 1966, he stated, "I want to do with my guitar what Little Richard does with his voice".

Steven Siro Vai (born June 6, 1960) is an American guitarist, songwriter and producer who has sold over 15 million albums. After starting his career as a music transcriptionist for Frank Zappa, Vai recorded and toured in Zappa's band for two years, from 1980 to 1982. He began a solo career in 1983, has released eight solo albums and won three Grammy Awards. He has also recorded and toured with Public Image Ltd., Alcatrazz, David Lee Roth and Whitesnake. Vai has been a regular touring member of the G3 Concert Tour which began in 1996. In 1999 Vai started his own record label Favored Nations, intending to showcase as he describes, "...artists that have attained the highest performance level on their chosen instruments."

Vai began playing guitar in 1973, at the age of 13. In 1974, he took guitar lessons from guitarist Joe Satriani and played in local bands, one of which was called "The Steve Vais". He was influenced by guitarists including Jimi Hendrix, Jeff Beck, Brian May, Jimmy Page, Glen Buxton, and jazz fusion guitarist Allan Holdsworth. Vai attended the Berklee College of Music, afterwards recording a promotional piece for them in which he spoke about auditioning for Frank Zappa at age 20.
