Bangladesh

The members used to meet every Friday at founder's home, where he had set up his own studio.

The group includes two two-time Bangladeshi national beatbox champions.

The group has nine members, but due to Eurovision's six-performer limit, three of them will not be able to appear on stage.

The song is performed entirely a cappella, with the group members recreating instrumental sounds using only their voices and beatboxing.

The last fully a cappella song at Eurovision was in 2011, while the last one to reach the Grand Final was in 2006.

During “Tumi Ele”, member Sykoverse mimics playing an invisible guitar, producing all the guitar sounds entirely with his mouth.
