The Yardbirds 1963. Crawdaddy Club impresario Giorgio Gomelsky became the Yardbirds manager and first record producer. Under Gomelsky's guidance the Yardbirds toured Britain as the back-up band for blues legend Sonny Boy Williamson II in December 1963 and early 1964, recording live tracks on 8 December and other dates. The recordings would be released two years later during the height of the Yardbirds popularity on the album "Sonny Boy Williamson and The Yardbirds". After the tours with Williamson, the Yardbirds signed to EMI's Columbia label in February 1964, and recorded more live tracks March 20 at the legendary Marquee Club in London.
Undercover (The Rolling Stones album) records, recent critical analysis has been kinder, noting the album's eclecticism and nastiness as a reflection of the Jagger/Richards feud.

However, the record is still one of the Stones' less popular and more obscure releases, although it managed to sell close to 3.5 million copies worldwide. "Undercover" was the last Rolling Stones album distributed in North America via Rolling Stones
