Former Blink-182 drummer Travis Barker and singer-song artist Adam “DJ AM” Goldstein were in critical condition with extensive burns Saturday after a jet crash the night before that killed four people, authorities said.

Two of the four who died late Friday were passengers and two were crew members, the National Transportation Safety Board said in a statement.

The NTSB has sent a Go Team to Columbia, South Carolina, to investigate the crash.

The Learjet 60 crashed on takeoff at the Columbia Metropolitan Airport at 11:53 p.m. Friday.

Beth Frits, spokeswoman at the Joseph Still Burn Center, in Augusta, Georgia, said Barker and Goldstein arrived at the hospital early Saturday. She said both men had “extensive burns.”

Barker and Goldstein had played at a huge free outdoor concert in Columbia’s Five Points district on Saturday night, CNN affiliate WIS-TV said.

Other acts at the concert included Perry Farrell, former of Jane’s Addiction, and singer Gavin DeGraw, Columbia Mayor Bob Coble told The Associated Press.
