Zozobra was an American sludge metal band that was first conceived by Caleb Scofield during 2006. He was joined by Santos Montano for the band's first release, Harmonic Tremors, in 2007. Early Zozobra recordings had a lot in common with the experimental-hardcore of Old Man Gloom and symbolically shares a synonymous name. Zozobra toured the United States with Isis and Jesu in early 2007.

Zozobra allowed Caleb Scofield the chance to write his own songs for the first time ever, unlike Cave In and Old Man Gloom.^[1]

Their second album, Bird of Prey, was released on August 5, 2008, and featured Aaron Harris of Isis on drums. Their third full-length, Savage Masters, was released on April 2, 2013.

Scofield died on March 28, 2018, but contributors to the band's recordings have played multiple live sets of Zozobra songs as a tribute to Scofield.
