'I sign for deaf people at gigs'
3 December 2013 Last updated at 00:12 GMT
Laura Schwengber, 23, is a sign language interpreter who sees it as her mission to bring music alive for people with hearing impairments.
She regularly appears on stage at gigs in her native Germany, signing her interpretation of the lyrics, tone and mood of the music.
BBC News went along to meet her at a recent concert of the German band Selig and the Deutsches Filmorchester Babelsberg at the Nikolaisaal in Potsdam.
Real Time is a series for the BBC News website in which ordinary people tell their own extraordinary stories.
