On July 19, the band performed their second single titled "Aik Nayi Subh", originally a literary piece by Ibn-e-Insha, on the fourth episode of the television series and got positive feedback from judging panel, which included, Fawad Khan, Meesha Shafi and Strings and allowed the band to qualify for the top eight bands round. Something Haute said, "the song, as corroborated by Meesha, had a very concert sound and the lead vocalist powerful vocals supported it thoroughly" and MangoBaaz cited that "due to Black Hour’s range and overall cohesion, the judges chose them to go to the next round." On July 26, in the next round of Pepsi Battle of the Bands, Black Hour performed a rendition of "Tum Hi Se Aye Mujahido" by Alamgir Haq and went into the top four bands round alongside Auj, Aarish and E Sharp. MangoBaaz reported that the cover song "rendition was goosebump-inducing and hit all the right notes" and Maheen Sabeeh, music critic, from The News International giving a critical review wrote, "Black Hour just couldn’t decide if they aim to entertain or carry their chosen genre forward full scale." In their final appearance at the show, Maheen Sabeeh from The News International said, "Black Hour went with an original called "Tanhaiyaan" with "Tanhai" by Fringe Benefits and showcased strong musicianship, picked good songs to mash", which received mix reviews from the panel judges, with Faisal Kapadia saying the performance was a “rollercoaster” ride.
