Rock guitarist Eric Clapton's reunion concerts with his former band Cream in New York made more than $10.6m (£6m), organisers said.
Cream formed in 1966 but split less than three years later
More than 56,000 people attended the three concerts at Madison Square Garden, which promoters said signalled Cream's parting of the ways once more.
Last week's shows, along with four in London in May, saw Cream's first return to the stage since they split in 1968.
Cream have sold more than 35 million albums worldwide.
Singles included Crossroads and Born Under a Bad Sign, I Feel Free and Strange Brew.
Tickets for the concerts in New York and at London's Albert Hall had sold out in less than two hours.
But publicist Kristen Foster said the band had no future plans.
