Christopher Michael Oliva (April 3, 1963 – October 17, 1993) was an American musician who was the lead guitarist and co-founder of the heavy metal band Savatage.

His main influences as a guitarist were Ritchie Blackmore, Tony Iommi, Uli Jon Roth and Michael Schenker.

In 1980, the duo met up with Steve Wacholz and jammed in a shack behind the Oliva home that was dubbed "The Pit" by the band.

"[Criss] had the fluidity of guys like George Lynch and Warren DeMartini, but with an aggressive, melodic conviction that fit Savatage perfectly."

"You could hear [Criss Oliva's] classical roots and appreciate his knowledge and grasp of modal dexterity that was such a huge signature of his work.

[citation needed] Savatage released their first two albums, Sirens in 1983, and The Dungeons Are Calling in 1985, both on Par Records, exhibiting a variety of musical styles.

In 1984, Oliva married Dawn Marae Hoppert,[5] his girlfriend since his time in middle school at Philippe Park near Safety Harbor, FL.

This was considered the "Golden Age" of Savatage, particularly when the band collaborated with producer Paul O'Neill for the first time in 1987's Hall of the Mountain King.

Oliva's unique playing style won him many fans, including Dave Mustaine of Megadeth, with whom Savatage toured in 1987 in support of Hall of the Mountain King.

Streets was Savatage's biggest mainstream success, and Oliva enjoyed the exposure the record gave the band, allowing new fans to be found for their music.

The face in the trees is supposed to be Jon Oliva, though producer Paul O'Neill disputes that despite its publication in an interview with Criss from 1993.

He was a combination of the angst of Duane Allman on "Layla,' the excitement of Jimmy Page, the emotion of Eric Clapton, the raw feel of Joe Perry and the dexterity of Eddie Van Halen or Allan Holdsworth."
