The concept for the album is “Resistance for freedom of expression through music via sixth sense.” Representatives of NegaNetwork explained, “This album focuses not only on their singing and performance. The members hope to convey their thoughts to the public through music. Their title track is an expression of the limitations of experiencing music with only five senses, and it asks people to feel it instead with their sixth sense. The song itself is very free in style.”
