It has been a decade and a half since Black broke out into the country's music scene with “Amar Prithibi”, introducing a generation of music lovers to the alternative rock genre. Much has changed since then, with the world and with the band. For starters, the two front-men of the band, Jon Kabir and Tahsan, have drifted away and have found their own careers, in the course of three more albums by the band.

After a five-year hiatus since their self-titled album in 2011, the band released their fifth studio album, titled “Un-Manush”, on Tuesday. In an album launch concert at the Russian Cultural Centre, three other bands – Poraho, Trainwreck and Beyond Blue – performed covers of popular Black songs for an energetic audience prior to the launch. The event also saw ample support from the music industry, with familiar faces Hamin Ahmed, Omar Khaler Rumi, Topu, Shaikh Shahed, Kazi Hablu and Prince Mahmood in attendance.

After the launch, the band performed songs of their new album for the audience.

The album features eight songs, including “Akkhep”, “Gohine”, “Odhora”, “Sommohon” and “Onek Jibon”. The band's lineup has two founding members – drummer Tony and guitarist Jahan, while Rubaiyat has joined the band as vocal and Charlz on bass, after a string of lineup changes.

The album was released under the banner of G-Series, and is sponsored by Banglalink.
