ESPN announced the music lineup for X Games Aspen 2017 on Wednesday. The lineup features four acts at the Buttermilk Ski Area venue Jan. 27 through 29, trimming the annual music festival to three nights from the four of previous years.

Bassnectar, the electronic-dance-music giant and brainchild of San Francisco-based DJ and producer Lorin Ashton, will headline Jan. 27. Bassnectar sold out a two-night run at Belly Up Aspen in 2014.

Jan. 28 will feature rapper, producer and drummer Anderson .Paak with The Free Nationals in the early show and the DJ duo The Chainsmokers as the closer following the night’s competitions.

San Francisco Bay Area rapper G-Eazy — the MC behind the hit “Me, Myself and I” — will close the festivities Jan. 29.

Tickets went on sale Wednesday at 
www.xgames.com. Four-show passes are $125 to $175. A Jan. 28-only pass runs $65 to $80. Prices for single concerts range from $25 to $30 for Anderson .Paak to $35 to $50 for G-Eazy and $45 to $60 for Bassnectar and The Chainsmokers.

Belly Up Aspen also announced its concerts for X Games weekend. The downtown club will host The Chainsmokers on Jan. 27 and both Anderson .Paak and G-Eazy on Jan. 29. Belly Up has not yet announced a Jan. 28 concert. Tickets for those shows are available at the Belly Up box office and http://www.bellyupaspen.com.

On the sports side, there will be 18 different disciplines in 2017. Women’s ski and snowboard Big Air competitions will grace the Aspen venue for the first time. ESPN reports that it’s the first time a women’s ski Big Air will be held at a U.S. X Games event.

Snow Bike racing is also new and will feature “modified dirt bikes which replaces the front wheel with a front ski and snowmobile track in place of the rear wheel. Snowmobile Best Trick will also return to the lineup for the first time since 2013,” according to ESPN.
