Charlie is taking a short leave from his band’s concert tour to be with his terminally ill mother.

Immediately following Thursday's show Kansas City, Charlie flew to New York to join his family at his mother's bedside.

Gene says he is honored to fill in for Charlie in his time of need:

"We are all metal brethren, and this is what we do... Charlie, we can't wait to have ya back where you belong, my man. I'm just keeping your throne warm for ya bro."

Watch some fan-filmed video footage of Gene Hoglan and Anthrax performing the band's classic song Caught In A Mosh at Expo Five in Louisville, Kentucky last Sunday:
