After a short stay in animation school, he met David Wexler aka Strangeloop (Erykah Badu, Skrillex, Flying Lotus). Through their friendship and collaboration, Particle Kid experienced a creative freedom in animation and filmmaking. “I feel in my element when it comes to video production, animation, and getting original content made.” For nearly a decade, through his production company (which also includes his wife Alex Dascalu Nelson aka Sisterlu), Spitball Pictures, he has created music videos and films for his own music projects as well as for other artists. His most recent productions include music videos for Edie Brickell & New Bohemians (“Tripwire” and “My Power”), Promise of the Real’s Anthony LoGerfo (“Love Commando”), folk-punk musician Sunny War (“Age of a Man“), GRAMMY award-winning Tinariwen (“Wartilla, Dan Caret Dub”), ukulele and guitar duo Folk Uke (“Small One”), and Neil Young (“Shape of You").

Particle Kid has also released six albums of his original music, including his April 2022 release Time Capsule, a 26-song musical journey through time, space, and consciousness. It features guest appearances from Jim James, Sean Ono Lennon, J Mascis, Margo Price, The Lovely Eggs, and Micah’s dad Willie Nelson on three tracks including "Die When I'm High (Halfway to Heaven)." His previous albums – self-titled debut Particle Kid, Everything Is Bullshit, Particle War, Window Rock, Live! Underground – are just part of the catalog of work Nelson has amassed with other artists and musicians. He often joins his brother’s band, Lukas Nelson & Promise of the Real, and is part of Neil Young’s band, touring and recording with Young as well as part of his full-length film Paradox. For Record Store Day in 2018, he released Lucky Wheel, a split 12” vinyl collaboration with punk legend and X co-founder John Doe. He created the cover art on Willie’s recent studio album First Rose of Spring. (Willie coined Micah “Particle Kid,” when he misspoke a “prodigal son” greeting.) On tour year round, Particle Kid has headlined shows around the world as well as opened for The Flaming Lips, Tinariwen, Margo Price, and Sheryl Crow, and been part of the line up for Luck Reunion, UTOPiAfest, and the Outlaw Music Festival.
As an industrial hemp activist, Particle Kid has served on the National Hemp Association’s Board of Directors, participates in Farm Aid events and their annual music festival, and combined the missions of both organizations by spearheaded a Change.org petition championing the Industrial Hemp Farming Act which became law in December 2018. Rolling Stone magazine hailed him as one of their “New Classics” – “The creative visionaries celebrated here come from the worlds of music, acting, comedy, sports and more. …they share a refusal to be contained by the rules of the past as they define the territory of the future.”
