Drummer Chris Adler exited Lamb Of God earlier this year for reasons he sums up as not being able to see eye-to-eye on certain things. Adler has since appeared on a Myrone track and has been doing drum clinics, and music business lessons, and live shows in India under the name The Chris Adler Experience.
You can check out Adler playing some Lamb Of God and Megadeth material at a recent Chris Adler Experience show in Bangalore. Given he was in both bands, it's not surprise he crushes it.
