BIGkids - comprising Mr Hudson and Rosie Oddie - will play at the Red Bull Bedroom Jam stage, which is the only outdoor stage at the entire festival.
Hudson will be joined by a selection of other artists, including four bands who were previously part of the Red Bull Bedroom Jam new talent project.
The musician said of the gig: "It's my first Camden Crawl - I can't wait! BIGkids will rock the Red Bull Bedroom Jam stage!!"
The Red Bull Bedroom Jam stage will be the only venue at the festival that does not require a full Camden Crawl ticket, and is also available to those under 18.
To get your free ticket and to find out more about the Red Bull Bedroom Jam project head to www.redbullbedroomjam.com/camdencrawl from today (May 3).
Camden Crawl runs from May 4-6 and will feature performances from the likes of Death in Vegas, The Cribs and Alabama 3.
