Important note: Robert Hazard's Out of the Blue CD was professionally manufactured by Disc Makers in Pennsauken, New Jersey. The CD is factory sealed in a cardboard sleeve. However, the CD was created from vinyl albums that were digitally mastered and transferred to CD. Digital filtering techniques were used to minimize background noise and other imperfections. Not all background noise and other imperfections were eliminated. Please do not purchase this CD if less than perfect sound quality will diminish your enjoyment of these extremely rare songs.
