Steppenwolf is one of the most legendary and at the same time most enigmatic bands in the history of rock music. On the border between mainstream and psychedelic underground, their song "Born to Be Wild" became the anthem of an entire generation. The new, hard sound of Steppenwolf was a stab in the heart of the "Summer of Love" and put an end to the hippie era. It is no coincidence that they were the very first band to use the word "heavy metal" in their lyrics.
Klaus Meine (born 25 May 1948) is a German vocalist, songwriter and instrumentalist best known as the frontman of the rock band Scorpions. Meine and guitarist Rudolf Schenker are the only two members of the group to appear on every Scorpions album, though he did not join the band until 1969, four years after its founding. Meine placed at No. 22 on Hit Parader's 'Top Heavy Metal Vocalists of All Time' list in 2006.
