They've raised over $145,000 dollars so far.
Green Day performed on Facebook Live yesterday to raise money for Hurricane Harvey relief efforts.
The hurricane has caused huge flooding in Texas, particularly in the city of Houston.
"We’re coming to you from Tampa, Florida right now," said the band.
"[The money raised] will go directly to Harvey relief, for the people that have been displaced in the tragedy that’s happened out there."
As it stands, they've raised over $145,000 dollars for Americares. You can donate here.
Check out the band's set here, including some older songs and a bunch of classics.
