Girl group aespa will release the four solo tracks performed by its members during the "SYNK: Parallel Line" world tour, the band's agency SM Entertainment said Monday.

The compilation, titled "aespa Special Digital Single 'SYNK: Parallel Line,'" will be released on Wednesday and will feature one solo track from each aespa member, all of which were performed during their concerts earlier this year.

Karina sang the hip-hop dance track "Up," for which she contributed to the lyrics, according to the agency. Giselle’s R&B track "Dopamine," Ningning’s R&B song "Bored!" and Winter’s EDM track "Spark" will also be included in the compilation.

aespa is also set to release its fifth EP, "Whiplash," on Oct. 21.

The girl group recently wrapped up the Asian leg of its "SYNK: Parallel Line" world tour with two concerts in Bangkok.

The tour will continue next year with stops in the United States, Mexico, Canada and Europe.
