Noh Taepung

On April 16, 2010, Noh Taepung debuted as a soloist with the digital single "1st Recollected Single". During early promotions, he was frequently compared to Korean singer Lee Seung Gi. Three months later, in early July, he appeared in now-deleted pre-debut content for TGN Entertainment's upcoming boy group, 20star, posted on the group’s official Daum Café under the stage name Typhoon.

However, in the official lineup announcement on July 27, he was listed as a former member, indicating his departure prior to the group’s formal reveal. Two years after an unannounced hiatus, on Febuary 3, 2012, he made a comeback under a new agency with his 1. 5th single, "Farewell".
