Arguably two of the biggest music newcomers in 2015 are teaming up for a tour this fall. Indie-pop band Echosmith and pop singer Rachel Platten will perform at the Tyson Events Center on December 17, 2015.

Echosmith is best known for their hit "Cool Kids" and "Bright." Rachel Platten is best known for songs "Stand By You" and  "Fight Song," which was number on on the Billboard Top 40 charts this summer. A third act will be announced soon.

The first 1,023 tickets are $20. After that, they will go up to $37 a piece. Tickets purchased on the day of the show will cost $42.

Tickets can be purchased online at TysonCenter.com or at the Tyson Events Center box office at 10:00AM on Saturday, Oct. 24, 2015.
