Nelly is all amped up for his newest album, Brass Knuckles. The Polow Da Don-produced album is due in stores June 4. The St. Louis rapper is excited for the new collection of songs, especially for his collaboration with Fergie on the single "Party People." "Energy," he told MTV News. "When I talk about energy, you got Nelly and Fergie, you probably got two of the most energetic people on the planet. And it's a straight rush." Nelly was able to wrangle together an impressive collection of guest artists including Usher, Ciara, Akon, Jermaine Dupri, the St. Lunatics and Avery Storm. Nelly however, was unable to get Bruce Springsteen to appear on Brass Knuckles. The rapper had reportedly reached out to the Boss, who was not available to cameo on the record.

Neil Young recently authorized the first in a "special edition" series of unreleased material. The album, titled Toast, is the result of an aborted Crazy Horse session recorded in San Francisco in 2000. The album lacks a release date as of yet, but according to Young's Web site, "Many songs share a bluesy, jazz-tinged vibe as a common thread. Three solid rockers are interspersed in the mix. Other songs are long with extensive explorations between verses, a Crazy Horse trademark." Young hits the road this summer for a string of gigs at several European music festivals, beginning with Rock in Rio Madrid on June 27.
