Scott Mercado was raised in Seattle, Washington, with his brother. He started playing the drums at age 11, as well as the dulcimer. He met Kevin Martin while they were both working on a project with Southern rock roots, called Uncle Duke. Both he and Kevin Martin formed the band Candlebox in May 1991. He left the band in 1997 in order to pursue his first love, jazz. Candlebox replaced him with Dave Krusen.
