All the Rock-It titles are boots. The Brian Macdonald was re-issued on the excellent Sony Rewind label and is the official release, the other is a boot. Would be very careful with the Robert Tepper, although it is being advertised as being on the Scotti Bros. label which is the correct one, so without seeing it couldn't confirm. The 2 Illusion dics to my knowledge have never been released on CD, so you decide their authenticity.
