Theessink began playing guitar in his teens, and by the mid-'60s he was part of a skiffle group. Skiffle music was quite popular in Ireland and England and other parts of Europe at that time, but once he heard Big Bill Broonzy perform on Radio Luxembourg, he had a revelation. He had never heard the guitar played so well by just one person, so it opened his eyes to the possibilities that blues and blues-based music could offer. He made a splash on the U.S. folk festival circuit in the late '80s, and Chicago-based Flying Fish Records issued his American debut, Baby Wants to Boogie (1987), which Theessink later re-released on his own label. A big part of his appeal as a performer and recording artist is his approach to cover songs. Rather than cover a Willie Dixon or Robert Johnson song to sound like the original artist might, Theessink takes an old gospel standard like "Will the Circle Be Unbroken," polishes it up, and makes it shine in his own way. His original songs offer up an outsider's perspective on places and things around the South that too many Americans take for granted.
Among Theessink's many fine albums are the aforementioned Baby Wants to Boogie, Hard Road Blues (1995), Journey On (1997), Bridges (2004), Songs from the Southland (2004), Slow Train (2007), Visions (2008), Delta Time (2012) -- the latter of which was a collaboration with Ry Cooder and Terry Evans -- and the 2015 concert LP True Blue. All of these albums were released on his own Blue Groove Records label and may be difficult to find in U.S. record stores, even ones specializing in jazz and blues. Theessink is based in Vienna when he's not on the road, and he continues to tour frequently around Europe, Australia, and New Zealand. The acclaimed Journey On and Johnny the Devil were remastered and reissued in 2016, precipitating a tour, and in 2019 his 70th Birthday Bash album was released and the subject of a television special. It featured the guitarist and songwriter with a cast of friends -- including the Blind Boys of Alabama, Ernst Molden, Jon Sass, Dorretta Carter, Champagne Charlie, and others -- delivering an overview of Theessink's long career with many folk-blues and gospel classics adorning the set list. ~ Richard Skelly, Rovi
