Aerosmith will be adding more European dates to its summer itinerary to follow up the booking at this year's Download Festival in England.

Effectively signaling a settling of differences with frontman Steven Tyler that had the other band members threatening to seek another singer -- temporarily, according to guitarist Joe Perry -- Aerosmith will precede its June 13 Download date with an appearance at the Sweden Rock Festival on June 10 in Solvesborg. A U.K. spokeswoman for the band tells Billboard.com that other European dates will be announced shortly.

"There's no Aerosmith without Steven Tyler," notes Download promoter Andy Copping of Live Nation U.K. "There's no point in entertaining anything other than (with) Steven Tyler." Copping adds that an Aerosmith without Tyler "was never part of the conversation" with the group's representatives.

The group has also been offered tour dates in South America, but nothing has been announced yet. No North American shows have been mentioned, and there's also no word on if and when Aerosmith plans to resume work on the new album it was recording in Brendan O'Brien, which was sidelined by Tyler and Perry's health issues.

Tyler has been in rehab since late December for an addiction to painkillers. Perry has been touring with his Joe Perry Project to support his latest album, "Have Guitar, Will Travel," while drummer Joey Kramer has been promoting his autobiography, "Hit Hard: A Story of Hitting Rock Bottom at the Top." Guitarist Brad Whitford is gearing up for an Experience Hendrix tour that starts March 4 in Santa Barbara, Calif.
