Idol rock group LEDApple, who recently wrapped up promotion for "Time Is Up", will be releasing new digital single "Sadness". The new track will depict a darker theme but packs a pop heavy beat and addictive melody.

On March 7th, the group's agency Startory Entertainment revealed LEDApple's charismatic concept photos. LEDApple seems to be slipping off their rocker boots and getting accustomed to their stuffed dancing shoes. The members wear simple suit with vivid colored handkerchief and ties, completely new concept from their casual rocker style for "Time is Up."

"Sadness" is composed by hit composer Jo Young Soo, the man behind T-ara's "Cry Cry". The track will be released on March 9th.
