Sunny Hill has finally made their return with a completely new image! They've been much loved for their emotional ballad style since their debut in 2007, but after two years of preparations for this daring change, they've also come back with two new members! Their title track, "Midnight Circus", is the work of composer Lee Min Soo and lyricist Kim Eana, the mega-hit combo behind hits like "Abracadabra" and "Good Day." As an acid jazz dance track, the song features an acoustic swing base, house beats, and an electronic sound - all with instruments personally played by the members themselves. Check out their comeback stage on M! Countdown below!
