This extraordinary artifact stands as one of the most coveted pieces in modern rock memorabilia: a KISS "Sonic Boom" CD Digipak hand-signed by all four active members of the legendary band — Gene Simmons, Paul Stanley, Eric Singer, and Tommy Thayer. Released in 2009 as KISS's first studio album in over a decade, Sonic Boom marked a thunderous return to form for the icons who defined arena rock, and this fully signed digipak captures that monumental moment in the band's storied legacy. Securing all four signatures on a single piece is a remarkable feat, making this an exceptionally rare find for any serious KISS Army collector or rock memorabilia enthusiast.

Each signature has been applied directly to the CD digipak sleeve in vivid, expressive ink, showcasing the unmistakable autographs of the Demon, the Starchild, the Cat, and the Spaceman. The authenticity of this item is beyond reproach, accompanied by a JSA (James Spence Authentication) Letter of Authenticity, LOA #ZZ80906 — one of the most respected and universally recognized third-party authentication certifications in the hobby. JSA's rigorous expert review process ensures every signature on this piece has been independently verified, providing collectors with absolute confidence in their acquisition. Whether displayed proudly or preserved as a blue-chip investment piece, this multi-signed digipak represents the full, iconic KISS lineup at one of their most celebrated modern milestones.

From the thunderous opening track to the electrifying closer, Sonic Boom reminded the world why KISS remains one of the greatest rock bands in history — and this hand-signed collectible is a tangible piece of that legacy. Opportunities to acquire a complete four-member KISS signed artifact with JSA certification are exceedingly rare on the secondary market. This is the definitive KISS collector's grail for devotees of classic rock history, authenticated memorabilia, and the enduring mythology of one of rock 'n' roll's most iconic acts.
