Maniacal Renderings is a 2006 release by Jon Oliva's Pain.

The album features material and riffs recorded by Jon Oliva's late brother, Criss.

Jon said that he moves around a lot and his wife found a box of old cassette tapes inside a shoebox, with Criss's handwriting on it.

Jon said that during their days in Savatage, the two would write, practice and record music, then swap so they could finish each other's songs.

He stated that there is plenty of material from the box that could be used in future works.
