There are some rare versions released of KISS latest album Sonic Boom!
The first one is this very limited Chinese 2-CD version of Sonic Boom. This 40 tracks edition (contains all the 11 tracks of the latest KISS album as well 29, kind off, best of tracks) comes in a wooden case with a slipcover! Very rare!
Another rare version is this limited Chinese release of Sonic Boom, this rare edition comes in a slipcase and has a different inlay, backcover and CD print!
The third rare version is this UK release with 4 badges, this version was only to get if you pre-ordered the CD!
All these versions are in my collection now…
