Oliver "Ollie" Riedel (b. April 11, 1971) is a German musician, most notable for being the bass-guitarist for the German Tanz-Metall ("Dance metal") band Rammstein.

Biography
Riedel was born on 11 April 1971 in Schwerin as an only child.
Growing up, Oliver had relatively good relationships with both of his parents. He attributes this to the small gap in between their ages. As a child, Oliver wasn't a good student, but he made his way through school with the assistance of his mother. Oliver was quite shy, especially during his teenage years, and while his friends partied at discos he would often be found just "hanging around".

Early years
In 1990, at the age of nineteen, Oliver began playing in a folk-fiddle/punk-rock band called The Inchtabokatables.

Musical career
In 1994, Riedel, Till Lindemann, Richard Z. Kruspe, and Christoph "Doom" Schneider entered and won the Berlin Senate Metro beat contest that allowed them to record a four track demo professionally. Paul H. Landers and Christian "Flake" Lorenz would later join the band they named Rammstein.
The six released their first album, Herzeleid (Heartache) in September, 1995. Their second album, Sehnsucht (Longing) was released in 1997, which would later become platinum.
In April 2001, the album Mutter (Mother) was released and a European tour followed, ending on 13 July 2002. It has been reported that at this time the members of Rammstein were seriously discussing whether to continue or not in their present form. It was decided that they should all take some time off and then reconsider whether to continue.
In 2003, Rammstein started work on the fourth album, which was to prove a turning point in Rammstein's sound and maturity. September 2004 saw the fruits of this work in the release of Reise, Reise ("Reise,Reise")

Personal characteristics
On the separation rumours
"We never wanted to, but after Mutter we had some difficult times because the third album is the most difficult one and we had a lot of pressure on us. We also had our differences between the group members and everyone's expectations were different. We took a year to rest, and after that we realized that we wanted to be together and to go on."
On his early family life
Interviewer: Did you have a lot of problems with your parents?
Ollie: Not a lot at all. My parents are quite young, which is good. Because the age difference isn't that big, we had it good with each other. My father and mother also liked the same music as me. We were almost more like friends than family.
Interviewer: But of course you did tease your brothers and sisters...
Ollie: No, because I don't have any, too bad. But if I would have had them, I would definitely have teased them!
