[1][2] The organization was co-founded in 2004 by Marc Brownstein, bass player for the popular electronic rock band The Disco Biscuits, and his friend Andy Bernstein,[3] author of The Pharmer's Almanac, a series of books about Phish.

These teams then set up tables at concerts through which they register voters and disseminate information related to political issues and upcoming elections.

[16][17] For the 2020 election, the organization registered roughly 400,000 voters, through its work with Ariana Grande, Spotify, YouTuber David Dobrik, and hundreds of other musicians, brands and partners.

[18][19][20] Although HeadCount is largely known for its on-the-ground work registering voters at concerts, and is a mainstay at festivals like Bonnaroo and Lollapalooza, the Coronavirus pandemic did not stop the organization's momentum.

[25] For the midterm elections in 2018, HeadCount also rolled out a campaign called "The Future is Voting" featuring a get-out-the-vote tour in college towns.

[26] Earlier that year, HeadCount ran the voter registration efforts for March for Our Lives, the organization created by students from Parkland, FL after the mass shooting at their high school.

The campaign has featured hundreds of musicians and entertainers posting "Register to Vote" photos on Facebook, Twitter and Instagram, with a link to an online voter registration form.

[1] HeadCount also partnered with Ben & Jerry's to hand out free ice cream on a Phish tour to fans that registered or pledged to vote.

Its blog features updates on "music, politics and everything in between,"[44] and it launched a platform called #SoundOff (www.SoundOffatCongress.org) for tweeting directly at members of Congress.
