Sung Si-kyung turns Ja, Oneureun into a sunset picnic concert
Sung Si-kyung brings Ja, Oneureun to Olympic Park 88 Grass Field on September 5-6, with Raisa joining Yang Hee-eun, Gummy and more.
Singer Sung Si-kyung will hold his brand concert '2026 Sung Si-kyung with friends [Ja, Oneureun]' for two days from September 5 to 6 at 6 PM at the Olympic Park 88 Grass Field.

Launched in 2022, this concert series has consistently sold out every show, but this year, it will step out of indoor venues for the first time to be held in an outdoor picnic format.
Recently, Sung Si-kyung shared the background for the outdoor stage via SNS, stating, "After taking a year off, I wanted to bring a bit of change to the 4th 'Ja, Oneureun.'" He added, "It might not feel like a perfect festival, but I hope it serves as a first step."
From Yang Hee-eun and Gummy to Indonesian star Raisa
The lineup includes vocalists such as Sung Si-kyung, Yang Hee-eun, Lee Jae-hoon, Won Mi-yeon, Kim Jang-hoon, Gummy, Kwon Jin Ah, and Kim Kwang-jin.
Notably, Indonesian singer Raisa, who released the duet 'HEAVEN KNOWS' with Sung Si-kyung last month, has been added to the lineup. The performance is expected to utilize the space of the 88 Grass Field to present a stage that harmonizes with the sunset.
