The Disco Biscuits, Umphrey’s McGee and STS9 will co-headline Cloud 9’s first Mayan Holidaze festival. A sister event of the Disco Biscuits/Umphrey’s McGee’s Caribbean Holidaze, Mayan Holidaze will bring the three jam-titans to the Mayan Riviera in Mexico from January 20-24, 2011. Though all three bands have toured together in various configurations over the past 12 years, these three groups have never co-headlined a destination event. Resort information will be revealed on May 5. All-inclusive early bird sales will begin on May 12.
