In 1997, their lead singer Nikolai Yordanov left and the band's popularity declined, which led to their dissolution in 2000.

Their first recordings, "Tryabva vsichko da priemam" and "Nai-vazhnoto", were for the 1988 film "Pred praga" (At the Doorstep).

The first song they played, "Ima" (originally released on Stariyat dub) appeared on the official compilation in 1990.

That year, BUMM was also reissued on cassette by Lazarov Records with the Pred praga songs and an unreleased version of Ne umirahme ot shtastie.

In 1996, they released a concert album called Punku nema'a umre (Punk's not gonna die).

With Stanoev, they released their fourth and final album, Pazete si decata (Save Your Children) in 1999.
