Colorado resident Nathaniel Rateliff joined other musicians Monday night to march in Denver, protesting Greenwood Village police in solidarity with Black Lives Matter.

Greenwood Village is best known in the music scene as the home of Denver's Fiddler's Green Amphitheatre, and while there isn't a concert season there this summer, a handful of artists are boycotting the venue.

On July 18, Rateliff tweeted a link to a petition to Greenwood Village City Council, demanding a repeal of Greenwood Village's Resolution 40-20.

According to CBS4 Denver, earlier in July, Greenwood Village passed Resolution 40-20, 'that shields Greenwood Village police officers from personal financial liability under Colorado’s new police reform law.'

'It is also an economic imperative that we as artists and fans will now refuse to spend our money in Greenwood Village,' Rateliff tweeted, before performing at the march and 'play-in' protest.

Rateliff was joined by The Lumineers' Wesley Schultz.
