How to get there

The Batavierhuis is easily accessible by public transport. Tram 8 towards Spangen leaves from Rotterdam Central Station and takes you to the Pieter de Hoochweg stop in 15 minutes. From there it is a few minutes’ walk.

You can also travel from Rotterdam Central Station by metro (line C or D). Change to line A or C at the Beurs stop and get off at the Coolhaven stop. From there it’s a few minutes’ walk.

You can also use an ov-fiets from Rotterdam Central Station and get there in less than 15 minutes.

Of course, the Batavierhuis can also be reached by car, but parking spaces in the area are very limited. If you really can’t get there by public transport or bicycle, it’s best to park in the Q-Park Schiecentrale car park. From there, it’s a 7-minute walk to the Batavierhuis.




Thomas van Geelen, a Tilburg native, started playing the cello aged ten at the local music school. While in high school he got drawn to other musical genres, progressive rock in particular. He learned to play the guitar and started playing in bands and with singer-songwriters. During his time studying Journalism, he decided to take his music making to a professional level.

He studied classical cello at the conservatory of Tilburg, took masterclasses with many great cellists and immersed himself into musical life, earning prizes in chamber music and band contests. Eventually he chose to combine his classical studies with jazz, hooking him up with some great teachers, to give way to his non-classical background. Meanwhile he also took arranging lessons. After getting his masters degree, he continued his studies at the conservatory of Rotterdam to further develop his jazz playing.

Thomas was selected twice for a carte blanche concert at renowned jazz venues in Breda, where he invited Oene van Geel, Ab Baars and others to play his own compositions. As a substitute, he frequently plays with the award winning Metropole Orkest. Furthermore he’s part of the crossover group Coal Harbour and the classical Bartolotti ensemble. As a studio musician he has recorded for David Guetta and David Garrett, among others.

Yanna Pelser


When Yanna Pelser, born in Delft, heard a recording of Händel’s ‘Arrival of the Queen of Sheba’ at the age of 5, her eyes started to sparkle. From this moment her love for music became clear and her parents decided to let her take violin lessons. In several(youth) orchestras she discovered the most beautiful orchestral music in the major concert halls of Europe while growing into an experienced orchestra and chamber musician. Drawn by the depth and warmth of the viola sound, she swapped her violin for a viola at the age of 14.

During her classical viola studies at the conservatories of Rotterdam, Tilburg and Detmold she discovered that her voice blended very well with her viola sound. From there she started developing the skill of singing and playing simultaneously. Currently she is composing new music for her debut album, on which the singing violist will be the center of attention.

Jazz-, pop- and world music are just as important to Yanna as is classical music. She is actively performing with jazz sextet Ikarai, and has collaborated with pop artists such as Duncan Laurence, Karsu, Celine Cairo and Flip Noorman. Yanna is often asked for studio work: she has recorded for David Guetta, Celine Dion, Will.I.Am and many more.

Pablo Rodríguez


Born in La Palma, Canary Islands, Pablo Rodríguez started to play the violin at the age of 6. Six years later, when one of his sisters gave him a Stephane Grappelli recording, he was enormously fascinated and quickly started to self-develop his own jazz language on the violin. This development turned out to be very useful in other music styles such as flamenco, folk and latin. Pablo has performed at several recordings, jazz venues and concert halls such as Heineken Jazz & más, Mercat de la música viva de Vic, Amsterdam Music Festival, Ateneo de Madrid, Auditorio Tenerife, Escola Tom Jobim (Brazil), De Doelen and the Alfredo Kraus Auditorium.

Besides his passion for jazz and improvisation, he studied classical violin in Madrid with violinist Alfredo García Serrano and in Codarts Rotterdam with András Czifra. At Codarts he also finished his master studies in Latin jazz with Christiaan van Hemert, Abel Marcel, Niti Ranjan Biswas and Anna Elis de Jong.

He has collaborated with a variety of artists such as Irene Álvarez (Cuadro Flamenco),  Jose Manuel León, Gordan Nikolić, Jorge Pardo, Carles Benavent, Pedro Díaz, Ima Galguén (arranger & composer), Pedro Sanz, Kike Perdomo, NEI-L, Voodrish, Nacho Aldeguer, Tim Kliphuis, Juan Carlos Pérez Brito, Domingo “Colorao” and Inma Galiot.
