The Stone Temple Pilots reunited with frontman Chester Bennington on Saturday night for the “From Classic To Rock” charity concert in California. The concert raises money for several schools in the state.

The two sides announced in November they had split on good terms. Bennington said he couldn’t put in the time for STP and his other band Linkin Park.

STP recorded one EP with Bennington called “High Rise” and released it in 2013.
