On April 27 1998, Madonna made an unannounced appearance at the 9th annual Rainforest Foundation Benefit Concert at New York City’s Carnegie Hall, where she performed Frozen with the East Harlem Violin Project, while wearing a Versace dress.

Jon Pareles from The New York Times felt that during this performance Madonna had “turned herself into America’s answer to Björk”.

Later that night, she wore a cowboy hat and joined various artists in a rendition of The Beatles’ With A Little Help From My Friends and Twist & Shout.
