K-pop girl band miss A

Korean pop groups 2AM and miss A will be performing as musical guests at labelmate 2PM's Seoul concert next weekend, according to their agency JYP Entertainment (JYPE) on Thursday.

"2AM and miss A gladly offered to be performing guests at 2PM's first concert despite their busy schedules", JYPE said in a press release. "Both groups are congratulating 2PM's significant first concert from the bottom of their hearts, and they will present the best opening performances for the audience".

2PM's concert will be held July 31 and August 1 at Seoul Olympic Park's Gymnastics Arena.

miss A, composed of Chinese members Fei and Jia, and Koreans Suzy and Min, made their debut in Korea on July 1. They are currently promoting their debut single "Bad Girl Good Girl", which has topped numerous online music charts in the country.

2AM is made up of members Jo Kwon, Jinwoon, Seulong and Changmin, who are known for their powerful vocals. The boys made their debut in July 2008 with the single "This Song" and gained popularity with several K-pop hits such as "Can't Let You Go Even If I Die" and "I Did Wrong" earlier this year.

Originally a seven-member band headed by Park Jae-beom, 2PM has been settling into a six-man act since Park left the group last September over the now-infamous "I hate Korea" comments he had posted on his MySpace pages during his teenage years as a trainee at JYPE.

The six members -- Junsu, Nichkhun, Taecyeon, Wooyoung, Junho and Chansung -- have since released "The First Album 1:59PM", their first record without Park, and single album "Don't Stop Can't Stop".

Tickets for the concert are available on websites Auction Tickets, Yes24 and G-market.
