From hip-hop to ska, BLOCK B's 2017 Montage EP highlighted the septet's appreciation for varying genres. Now sentimental R&B gets added to the mix with its rerelease, Re:MONTAGE. With lush guitar and drums, "Don't Leave" is a last-chance plea where the guys put ego aside and pine for a lover. U-Kwon delivers a smooth, falsetto-driven ode to a girl on the electro-R&B cut "Everythin'," while Jaehyo gives a powerful, belting performance on the heartbreaking piano ballad "At Last," adding three new love stories to BLOCK B's diverse discography.
