Why did the glass organ, extremely popular in the 18th and 19th century, almost completely disappear from the globe? The story goes that the thin, hypnotic sound of the singing glasses can bring about a state of trance. Some people would even have gone insane... 

Rogier Kappers, the Glass Grinder, collected hundreds of glasses and built the only glass organ of the Netherlands. On his transport bike, he rambles around, showing up on festivals, village squares and street corners, telling stories and enchanting his audiences with old and new songs -from Bach, Beatles and Brel- on the singing glasses.  

Glass, My Unfulfilled Life is a long documentary about Rogier's glass carreer. The film is just released and has been received very well. It won a Golden Alexander Award at the renowned International Thessaloniki Documentary Festival and was nominated for Best Dutch Documentary at IDFA 2023. It is selected on many filmfestivals wordlwide. Rogier also performs in combination with a filmscreening. For more information about the documentary, look here.

The Show

“ Mesmerising...”     (ARD, German tv)  
 “ Unbelievable...”    (Podium Witteman, Dutch tv)  
“ Virtuoso...”              (Top 2000 a go go, Dutch tv)  
“ Pure magic...”        (Dubai Int.Street Festival)  
“ Goose bumps...”    (Audience reaction)

My show (25 minutes) is a combination of music and storytelling. 

Rogier is standing behind his organ. A large glass rotates slowly and produces a deep drone tone. Rogier introduces himself, and tells that as a small boy he was already fascinated by the singing glass. Slowly, he starts playing on top of the drone tone. The sound of the glasses immediately captivates the audience. From here the performance takes off. Rogier has a varied repertoire of pop-evergreens and classical music. In between, he tells stories about his journey of discovery on glass. His repertoire includes music by The Beatles, Bach, Jacques Brel, Oasis, Abba, Simon & Garfunkel, Arvo Pärt, and songs like Summertime and House of the Rising Sun. At the end of his show, he invite the audience to have a look up close at the organ. People are curious and ask questions. They can try out to make a glass sing by themselves.

Special shows and collaborations
On demand, I offer special shows, longer or shorter. For example with only  classic repertoire, or repertoire more focused on pop songs and sing alongs. A very special place has the music of the Estonian composer Arvo Pärt. I am passionate about his music, and his pervasive minimalist compositions seem to fit very well on glass. I compiled a small program around Pärts music.

I work together with other musicians and artists, for example:
The Evening of Film Music, with the world renowned Dutch Metropole Orchestra
* Arrangements and live music (Glass & Piano) with silent films in the 'Eye National Film Institute' in Amsterdam
* Music for 'The Courage of Despair', a show by Dutch comic Hendrick Jan de Stuntman
* Live Performance with puppeteer Heike Klockmeier, Ambrella Figuren Theater (DE)
* I worked together with musicians who play instruments like the cello, violin, guitar, piano, singing saw etc.

It’s a great discovery tour to find out which music fits well to glass. There is some music written for glass, even by composers like Mozart and Beethoven, but it's not much. And actually, my challenge is more to find and re-arrange songs and compositions which were never played on glass before. How would SOS from Abba sound, or Stairway to Heaven from Led Zeppelin. And Cohen,  Brel, the Beatles? And singing with the glasses, how does that sound?

Next to pop evergreens and chansons, I re-arrange work of classical composers for glass: Bach, songs from Schubert, Schumann, and above all the music form the  renowned Estonian composer Arvo Pärt. His pervasive minimalist compositions really seem to fit well to the sound of glass. 

A Music Album
The coming year, I will be working on a music album in which I explore the possibilities of glass music in combination with other instruments and (harmony)singing. It will be a combination of adaptions of existing songs, and original compositions. Inscribe on my mailing list to be kept updated.

About Me

Music has always been important in my life. I play piano (as an amateur) since an early age, and later the accordion and guitar were added.
I worked as a documentary film maker for many years, and made several films on music. My 'moment of fame' was my feature-length music documentary Lomax the Songhunter.  It was awarded with many prizes, among them a Golden Calf (Best Dutch documentary of the year) and an international  Emmy award nomination. 

Making music myself kept pulling me. As ten-year-old boy, I had seen a glass organ on television. The mesmerising and hypnotic sound touched something deep inside of me, and the idea to build one myself has been there since. At age 52, I decided to turn the wheel of my life and do it! Nobody believed me, but I persisted. It was an amazing journey of discovery. I collected hundreds glasses from shops all over the country,  and started to build, rebuild, finding repertoire, rehearsing... I progressed slowly but steadily.

And now, 7 years later, I can live partly from my performances with the glasses. At the same time, I'm making the documentary 'Glass' about this seven year adventure  for Dutch
(KRO/NCRV) and international television . It will be released and broadcasted in 2023. Join my mailing list  and I will keep you updated.

Playing for 10.000 people, scary...

Tour Dates

I don’t want anything else anymore, only spin and grind my glasses, and let all and sundry listen to it. Since 4 years, I am touring the cities and countryside of Europe, playing on festivals and on the street. I played for example at Oerol / Netherlands, La Strada Bremen / Germany, Out There/ UK,  Kleines Fest /Germany, Tollwood/ Germany, International Street Festival  Dubai etc.  

But I also love to play as a busker, just out on the streets, so you might find me next to your grocery store, at the train station,  in front of the IKEA on your saturday out, or in a small off track street in some provincial town.
