Aerosmith has just taken off for a tour of Europe, but it apparently had quite a busy week prior to leaving the States.The band is rumored to have recorded a new song for an unnamed soundtrack with producer Jack Douglas at the helm in New York last weekend, although those involved are remaining tightlipped about the project. A spokesperson for Douglas confirmed that his client had been working with Aerosmith but declined to cough up any details. The group's publicist was unaware that the band had been recording, and its management was unavailable for comment. Douglas had previously produced the Aerosmith's "I Don't Want To Miss A Thing" for the "Armaggeddon" soundtrack. Aerosmith also performed at a Boston radio station concert on June 5 and joined Run-DMC on stage for a rendition of "Walk This Way," which was a massive crossover hit for the metal/hip-hop team in 1986. Meanwhile, Run-DMC has issued a press release confirming that Aerosmith is expected to join them in recording a remake of the rap group's '86 hit, "It's Tricky," with producer Rick Rubin, although a spokesperson for the rappers tells MTV News that the recording schedule is yet to be set. The music is ready, but Run-DMC may have to head to Europe to cut the vocals to accommodate Aerosmith's busy schedule. Meanwhile fans needing an Aerosmith fix this fall may want to check into a tribute album to the band, titled "Not the Same Old Song and Dance." Producer Bob Kulick reports that the track highlights feature a cavalcade of artists from the '70s and '80s and include "Back in the Saddle," with Mark Slaughter, Albert Lee, and Quiet Riot's Rudy Sarzo And Frankie Banali; "Rag Doll," with Ted Nugent; "Chip Away the Stone" with Vince Neil; "Sweet Emotion" With Jack Blades, Tommy Shaw, Mike Inez and new Motley Crue drummer Randy Castillo; "Draw the Line" with ex-members of Tesla, Tony Levin And Eric Singer; "Dream On," with Ronnie James Dio and Yngwie Malmsteen; "Same Old Song And Dance," with Jack Russell, Jeff 'Skunk' Baxter, Jeff Pilson, and Bobby Blotzer; "No Surprise," with Jani Lane and Joe Perry's Son Adrian; "Toys In The Attic," by Stephen Pearcy, Tracii Guns, and drummer Aynsley Dunbar; "Walk This Way," with Fee Waybill, Tim Bogert and others; and "Last Child," sung by Starship's Mickey Thomas with Earl Slick on guitar. The record is due out September 7 on the Cleopatra label. Meanwhile, Aerosmith's European tour kicks off on June 10 in Stockholm. The group will return to the States to play Woodstock June 23-25, which will be the last tour date in its "Nine Lives" cycle. Unfortunately, the group won't be making up any of the shows it was forced to cancel after a flu bug swept through its ranks last month (see "Aerosmith Gets Back On Track After Missing Tour Dates"). Fans in Phoenix, San Francisco, Bakersfield, and the Seattle areas were issued an apology via the official Aerosmith Web site.
