Questlove is such a wonderful guy that it’s hard to believe anyone would want to piss him off. But apparently someone did. The Roots pulled out of two David Bowie Tribute shows over what Questo’s describes as “Bitchassness.”

The Philadelphia hip-hop band was expected to perform at two David Bowie tribute concerts at New York’s Carnegie Hall on March 31 and another one at Radio City Music Hall on Friday (April 1). In a lengthy Instagram post, Questlove explains why they won't be there.

"Mood. I've never been so insecure or petty as to deny a fellow musician use of ANY of my equipment (or my band's equipment----or resources or contacts or knowledge or ANYTHING) it angers me when that same courtesy is not reciprocated," he wrote before adding that Bilal, Kimbra, Wendy Melvoin, DD Jackson and Ray Angry would not be performing in the two shows as well.

According to the Associated Press, Questlove and The Roots backed out of the events after Holy Holy, a rock supergroup that performs the musical works of David Bowie, wouldn't share equipment during a rehearsal.

There's no official word if The Roots will perform at the Bowie tribute show at Radio City Music Hall.

In the end, we learn two things: Don't piss off Questlove and sharing is caring.
