Aerosmith are set to resume the 'Let Rock Rule' tour. Today (Aug. 15), the band said that the band will perform their concert at the Gorge Amphitheater in Gorge, WA tomorrow night now that drummer Joey Kramer has undergone what a press release called a "minor medical procedure."

“I'm feeling better than ever and I’ll be back sitting in the best seat in the house, hitting it harder than ever for our amazing fans," he said. "My gratitude and thanks for all the love and support showered on me during this time. #LetRockRule.”

On Wednesday, the band announced that they had canceled that evening's show at the Concord Pavilion in Concord, CA due to Kramer's need for immediate medical assistance. Although the press release did not specify what illness caused the cancellation, it refuted TMZ's anonymously sourced claim that Kramer has a history of heart problems.

The Concord date was the only concert affected. The 'Let Rock Rule' tour, with Slash as the opener, will continue through mid-September.
