"Freak Out" debut album signed on the cover in blue ballpoint pen by Frank Zappa & the Mothers of Invention front man Frank Zappa. Measuring approximately 12" x 12" and in very good condition, with some signs of scattered wear. Accompanied by a full Letter of Authenticity from ACOA (#SA59156). As the groundbreaking 1966 debut from Frank Zappa and The Mothers of Invention, “Freak Out!” is widely regarded as one of the most influential and experimental albums of the psychedelic era, helping redefine the possibilities of rock music. Signed examples from Zappa—whose autographs remain highly sought-after following his passing in 1993—are especially desirable on seminal early titles such as this landmark debut release.
