Blind Vertrouwen | Jos Bloemkolk, Theo van Duijl en Roland Vonk

Blind Vertrouwen is the trio of Rotterdammers Jos Bloemkolk (vocals), Theo van Duijl (guitar), and Roland Vonk (bass guitar and stories).

Jos and Theo caused a sensation in the late seventies and early eighties with the Dutch pop band Noodweer. They even had a modest hit in 1983 with the more or less satirical song 'In de disco'.

Roland Vonk was one of the voices of Radio Rijnmond for many years, with his own programs such as Archief Rijnmond and Het Opkamertje. He took early retirement at the end of 2025.

Since 2025, the gentlemen have been performing as a close-knit and energetic trio with their own Dutch-language songs and stories about city life, family, aging, and the temptations of life. Thanks to Roland Vonk's predominantly autobiographical and reflective stories, a Blind Vertrouwen performance in the theater is truly a show.
