Make Music Day, the annual global celebration of music occurring each June 21st and featuring over 4,000 free, outdoor concerts, music lessons and jam sessions in over 60 U.S. cities, has announced its lineup of artist ambassadors. The all-day musical celebration on the summer solstice brings people of all styles, ages and skill levels together to make music.

Make Music Day ambassadors include (in alphabetical order) Carmine and Vinny Appice, Brian Chase (Yeah Yeah Yeahs), Peter Cincotti, Charles Esten (Nashville on CMT/Hulu), Philip Glass, Daniel Ho, Mandy Jiroux, Glenn Kotche (Wilco), Lenka, Christian McBride, Ian Mellencamp, Taylor Momsen (The Pretty Reckless), Graham Nash, OK Go, Lee Oskar, Alex Skolnick, Tokyo Police Club, Us the Duo, Suzanne Vega, Vintage Trouble and Bernie Williams (former New York Yankees centerfielder and Latin Grammy nominated artist), along with many others to be found across the global celebration.

“What I love about Make Music Day is that it brings music out to the public with no barriers or boundaries,” says Christian McBride. “On June 21st, you never know what you might hear – a jazz trio on a train platform, a funk band in a prison, or a string quartet on a porch. They’re celebrating every kind of music and bringing people together.”

“By uniting music makers from every walk of life, it reminds us that music is bigger than any one culture, viewpoint or experience and that we can revel in being humbled by it,” states Dave Monk of Tokyo Police Club.

“Why do we love Make Music Day?” asks OK Go. “Because for one day of the year music gets to run free in the streets in all of its most insane and mundane permutations.”

Us the Duo adds that, “Although music is constantly happening all around us, Make Music Day celebrates it in one glorious day of sound-making in the streets of a city or town near you.”

“What I love about Make Music Day is that it brings music out to the public with no barriers or boundaries.”

Charles Esten notes, “You think you’re someone who ‘can’t make music?’ I think you might just be someone who hasn’t explored all the ways that you could. Spend a couple hours in a music store. Try instrument after instrument. Don’t be self-conscious. Just have fun. You’re not playing for anybody else. You’re playing for yourself. So keep trying.”

The artist ambassadors will be sharing their love of music, and music making, with their fans and the public in the days leading up to Make Music Day.

Completely different from a typical music festival, Make Music Day celebrates and promotes the natural music maker in all of us, regardless of ability. Every kind of musician – from bucket drummers to opera singers – pours onto streets, parks, plazas, porches, rooftops, gardens and other public spaces to share their music with friends, neighbors and strangers.

Make Music Day national highlights include Sousapaloozas that bring together hundreds of brass and wind musicians to play the music of John Philip Sousa, Street Studios that feature DJs and producers bringing gear and engaging passersby in the spontaneous, collaborative production of original music on the street, and more than 175 Mass Appeal events that bring together musicians of all levels and ages to make music in large, single-instrument groups led by experienced facilitators.

Cities hosting major celebrations include New York City, Los Angeles, Boston, Chicago, Cleveland, Detroit, Fullerton, Madison, Milwaukee, Minneapolis-St. Paul, Nashville, Pittsburgh, Portland (OR), St. Louis, San Jose, Seattle and the entire states of Vermont and Rhode Island, with smaller festivities taking place in other communities nationwide.

Make Music Day, which began in France in 1982 as the Fête de la Musique, has since grown to more than 750 cities cross 120 countries, and is presented in the U.S. by The NAMM Foundation and coordinated by the nonprofit Make Music Alliance.

All Make Music Day events are free and open to the public. For the full schedule of events in each city and to register to perform or host musical events, please visit makemusicday.org.
