Bruce Springsteen and Jon Bon Jovi are to perform at a benefit concert for victims of Hurricane Sandy on Friday.
The rock stars are natives of New Jersey, which was one of the areas hardest hit by the storm.
They will be joined by other stars including Billy Joel, Sting and Christina Aguilera on the live one-hour telethon to be broadcast on NBC.
Money raised from Hurricane Sandy: Coming Together will go to the American Red Cross relief efforts.
Hosted by Today show presenter Matt Lauer, the concert will be recorded from NBC's New York studios at Rockefeller Plaza.
It will be broadcast live across NBC's other cable networks including Bravo, CNBC, E!, Syfy and USA at 20:00 EST (00:00 GMT) and tape-delayed on the west coast.
The commercial-free telethon will also be streamed live on NBC's website.
Making the announcement on his morning programme, Lauer added more acts would be announced on Friday.
President Barack Obama visited New Jersey on Wednesday to see the worst affected areas after the storm hit on Monday.
More than 70 people were killed in the US, while some 20,000 people remain trapped in their homes by sewage-contaminated floodwater.
NBC organised a similar benefit after Hurricane Katrina in 2005 which raised $50m (£31m) for the Red Cross.
