- Triks and The Paramounts - Doe Maar Net Zoals Ik (1966)
- Karin Kent - Als Ik Een Jongen Was (1964)
According to the Liner Notes translations page on the excellent Cutie Morning Moon site:
After winning a talent contest singer Triks Boelen started her career as vocalist for the very popular Maskers. When Bob Bouber joined this band she had to leave. The band she started next was called the Paramounts, but was later re-christened Triks & the Paramounts. The band came from Amstelveen and was fairly popular in the Amsterdam area but had no nationwide fame. This changed a bit when they (with the Fouryo’s and Andre van Duin) opened for the Rolling Stones on August 8th, 1964 at the Scheveningen Kurhaus. On that occasion the band consisted of: Triks Boelen (voc), Ronald Fens (guit), Rob Gerrand (bass), Hans Keijser (org) and Wim v. Taarling (drums). The Paramounts only released one official singles (for Delta) and some recordings for commercial records like Lion Tops and Oko.
From the liner notes to Beat Express #2 - Amsterdam. There's a bit of interesting background on the 60s Amsterdam beat scene on that page too.
More on Triks & The Paramounts here.
I had no luck finding anything in English on Karin, but there's a biography and discography in Dutch here.
EDIT: Please check the comments for Bruno's very helpful translation of the biography above.
Both tracks are from Biet Het Volume 3: From the Kitchen To The Garage.
