Shellenberger, 39, was diagnosed with a malignant glioma brain tumor last May and performed with the band until last fall. His chemotherapy treatment was reportedly documented on “ABC World News Tonight” last May.

Although initial reports do not say where Shellenberger died, he was “surrounded by his loving family, the band and close friends,” according to a statement.

Lit’s 1999 debut album, A Place In The Sun, was a bestseller including three hit singles that includes “My Own Worst Enemy,” which still sees rotation on modern rock radio.
