Jakarta. American boyband Why Don't We are set to hold their first concert in Indonesia with their Eight Letters Tour Live at Kota Kasablanka Mall, Jakarta, on Nov. 21.

David Ananda, the managing director of Full Color Entertainment, said the ticket presale showed overwhelming enthusiasm for the five young singers – Jonah Marais, Corbyn Besson, Daniel Seavey, Jack Avery and Zach Herron.

"The presale tickets were sold out within a matter of minutes. But people who couldn't get one don't need to worry, the regular tickets are still available on Book My Show. [The tickets] can also be bought offline at the Full Color Entertainment booth at Mall Taman Anggrek Jakarta," David said in a statement on Friday.

Before they made their debut in 2016, the members of WDW were already budding social media stars whose popularity propelled the band to fame within less than two years.

Since then, the group has released five mini-albums titled "Only The Beginning" (2016), "Something Different," "Why Don't We Just," "Invitation" and "Why Don't We Christmas" in 2017.

The current tour is named after their first full-length album, "8 Letters," which tells the story of the struggle to confess one's true love.

The Overtunes, an Indonesian pop band made up of three brothers – Mada, Reuben and Mikha Brahmantyo – will open for WDW.

Mikha said the local band looked forward to learning from the American pop boyband and WDW's production team, particularly in their concert preparation.

"Hopefully, we can take lessons from WDW's production team in preparing a concert. We've seen other bands really benefitting from an excellent production team," Mikha said.
