Metallica went for the rare and deep cuts as they celebrated their 40th anniversary over the weekend.

The legendary heavy metal band played the 1997 single “Fixxxer” for the first time live as they performed at San Francisco’s Chase Center.

“After 40 years, there’s still firsts,” lead vocalist James Hetfield said.

They also performed “Trapped Under Ice” and “The End of the Line” as well as a few fan favorites including “Nothing Else Matters” and “Sad but True.”

The band was inducted into the Rock and Roll Hall of Fame in 2009.
