Vrienten began his musical career in the late 1960s as a member of local group Les Cruches. In the early 1970s he wrote songs for others and released his first single as Ruby Carmichael. In 1977, Vrienten released his debut solo album Paul Santos. In 1980, he joined the band Doe Maar, one of the most popular Dutch bands ever.

In 1994, Vrienten began working with Harry Bannink, who had been composing for Sesamstraat since the beginning of the show. After Bannink's death in October 1999, Vrienten became the sole composer for Sesamstraat.
Like Bannink, Vrienten is a versatile composer and is capable of using a variety of music styles. He composes and records most of the music for the show in his home studio, playing piano, guitar and bass, and working with session musicians when needed. Often he can be heard in the background or singing harmony.
