Metal met rap when the band Anthrax teamed with Public Enemy for a new version of the latter's hit "Bring the Noise." Here Anthrax guitarist Scott Ian, center, performs with Chuck D and Flava Flav of Public Enemy perform on stage at the "Rock The Bells" tour in July 2007 in New York.
Aerosmith and Run DMC perform in August 2002. Run DMC covered the rock group's "Walk This Way" on their "Raising Hell" album in 1986. It is the grandfather of all "rock rap."
Tony Bennett's 2011 "Duets II" album featured a bevy of stars including Lady Gaga, Carrie Underwood, Aretha Franklin and Andrea Bocelli. But it was his rendition of "Body and Soul" with Amy Winehouse that stirred the most interest, because she recorded it just months before her death from alcohol poisoning in July 2011.
After recording their 2009 hit "Over and Over," country singer Tim McGraw and rapper Nelly linked up again, this time to film a Budweiser commercial.
The 2000 film "Duets" found Gwyneth Paltrow and Huey Lewis collaborating for a cover of "Cruisin" that went to no. 1 in Australia.

The bluegrass singer Alison Krauss and rocker Robert Plant came together for the 2007 album "Raising Sand." In 2009 the project won the album of the year Grammy.
More than a few folks scratched their heads when it was announced that Paul McCartney was working with Kanye West on the rapper's single, "Only One." The pair performed with Rihanna at the 2015 Grammys.

Sylvester Stallone and Dolly Parton recorded "Sweet Lovin' Friends," a duet for their 1984 comedy "Rhinestone." Both the song and the film flopped.
"Come with Me" by the artist then known as Puff Daddy found him working with rocker Jimmy Page in 1998. The song appeared on the soundtrack of the film "Godzilla."
