In the early days he was the singer of rock- and popbands Horizon and Remedy. Moving from southern Sweden to Gothenburg in the mid -90s he started singing with afro beat band Bokaloho. Keyboardist David Bäck was one of the founders of that band and in the early -00s David and his brother Anders Bäck invited Benyam to jam at their jazzclub St:Georges. These evenings gave Benyam the inspiration to start writing music for his first album "for the Love in My Neighbor's Eye" which he released under the name "Benyam & the Bullydrops" in 2009. The Bullydrops were at that time the Bäck Brothers, Mats Eriksson, Victor Furbacken, Matti Ollikainen, Thommy Larsson (though Chris Montgomery replaced Larsson during the recordings), Samuel Olsson and Markus Ahlberg.
In 2010 Benyam organized the project "Brothers and sisters of Dawit" and the recording of the song "Relese him(song for Dawit)" to raise opinion and awareness regarding the situation of Swedish citizen Dawit Isaak imprisoned without trial in Eritrea since 2001.
In 2011 Benyam released "Guiding Light
" his first album under his own name. The musicians were: Anders Augustsson, Johan Johansson, Stefan Bellnäs and Chris Montgomery.
Two singles "Real Love" and "Separating Us" released in 2017 marks the return of Benyam Lemma.
