Ströer studied music theory and piano at the Richard Strauss Conservatory in the 1960s and then at the Hochschule für Musik in Munich.
In the early 1970s, he became bass player in the Bobby Jones Trio, but he achieved greater fame from 1975 onwards as bassist in the Mild Maniac Orchestra of Volker Kriegel, to which he belonged until the mid-1980s, also to be heard on Biton Grooves [de].
At the same time, he became a sought-after studio musician and participated in recordings by Eberhard Schoener, Falco, Donna Summer, Amanda Lear, La Bionda and Gilbert Bécaud.
In addition, he was active as a music producer (including for Udo Lindenberg's albums between 1986 and 1998, which received several Goldene Schallplatten).
