Kathleen Hanna, David Yow & Ariel Pink will record a personal message for you on Cameo
Cameo, the web service where you can get celebrities to make personalized videos, has become very popular since launching in 2016, with over 30,000 famous people on the platform. Amongst the actors, comedians, reality stars, celebrity chefs, sports figures and other types you might expect to be on Cameo are a few indie rock artists you might not. One of those is Bikini Kill / Le Tigre / Julie Ruin's Kathleen Hanna who says in her profile, "So excited to connect with you all!...I can’t do cover songs at the moment but am happy to do bits of my own songs!" Though Kathleen is "temporarily unavailable" she notes that she's donating all the proceeds to the Peace Sisters organization which is pretty cool.
Another you might not expect is Jesus Lizard / Scratch Acid frontman David Yow, who writes in his Cameo profile, "I did punk rock for a LONG time. Now, acting kinda spins my prop more." (Get him to plug your noise rock album!) More from the "indie" tag on Cameo: Ariel Pink, who refers to himself as "American idol audition outtakes star"; Torres, Foxygen's Sam France, Dr Dog's Eric Slick, The Drums' Jonny Pierce, Giant Drag's Annie Hardy, Surfbort's Dani MIller, Brad Oberhofer, and Girlpool's Harmony Tividad. You can watch examples of their videos on thier Cameo profile pages.
Also under the "indie" category's is Creed's Scott Stapp. Did he tag himself indie?
