Island City is a 3/4 all female rock band that formed in 2004. Their style is what I would probably be likely to say indie-rock. K-Pop fans might recognize them from their God of Study OST stint singing: Starry Night.
Island City started as a club band at Hongik University and made their way through the clubs in Hongdae before making their first EP.
Sang Jee-Hee is on vocals:
Aleum (Beautiful) plays the bass:
Yeon-Soo is on guitar: I wonder if he feels like the odd-man out? He also had some solo work out in 2009 on the album Dream of Ocarina (Is he Link?)
And following up with Sang-Min on drums:
Love Story (2006)
Chili Sauce (2008)
And their full length debut album:
Island City (2010) (Mnet Media)
Here is their song: 난 유쾌한 당신의 공주를 꿈꾼다 (I'm Entertaining the Princess of Your Dreams)
I also really like this acoustic version of theirs:
