Maniacal Renderings is a 2006 release by Jon Oliva's Pain. It was their first full-length studio recording released for new label, AFM Records.
The album features material and riffs recorded by Jon's late brother, Criss Oliva. Oliva says 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 says that during their days in Savatage, the two would write, practice and record music, then swap so they could finish each other's songs. Jon says that there is plenty of material from the box that could be used in future works.
