Last year Berlin singer/songwriter Martin Goldenbaum released his fifth album „Optimist“.Its witty and provocant German lyrics are combined with groovy pop and rock melodies and a hint of rockabilly. In 2005 he released his debut solo album „Rätselraten“ under his pseudonym Martingo which was followed in 2006 by second album „Leises Lauschen“. To be independent he founded the music label „Gold und Tier“ together with Johanna Zeul in 2009 when he also released his third album „Bügeln mit System“. In 2011 Martingo abandoned his artist name and presented himself as Martin Goldenbaum. He was part of several TV and radio shows and performes at 70 to 90 concerts every year.
