From Allkpop cause I don't have time to write this out right now, but thought others might be interested in them. (I'd probably forget to do this later once I got home.)
Comprised of Kim So Young (vocal), Kim Mi Jung (guitar), Lee Hwa Yeon (bass), and Jang Hyun Ah (drums), Sweet Revenge was nicknamed as the “SNSD of Hongdae” because of Kim So Young’s resemblance to SNSD’s Taeyeon. Sweet Revenge have released two EP albums since their indie debut in 2009, and created a strong fanbase for themselves in Hongdae.
Their mini album released on August 25th contains four tracks, including the title track, “Rule Breaker”, “Space Monster Intro“, “Space Monster“, and “Love Virus“. Surprisingly, the title track was written and composed by the members themselves.
