While performing at House of Blues in Boston on Tuesday night (Sept. 12), the rapper, aka Austin Richard Post, broke out a bedazzled acoustic guitar for a cover version of “All Apologies.”

The Boston show kicked off the Malone’s North American tour (after a couple of festival appearances earlier this month).

Check out fan footage of the performance, which contains a bit of profanity, now at Radio.com. See all of Post’s tour dates below.
