Fay Claassen & Koosje: Get Happy!

Acclaimed Dutch jazz singer Fay Claassen joins forces with rising vocalist Koosje for Get Happy! at LantarenVenster in Rotterdam on Sunday 21 March 2027. Bringing together jazz, soul, pop and inventive vocal arrangements, the two singers present an intimate concert filled with familiar songs, original compositions, unexpected duets and plenty of musical chemistry.

The collaboration began in May 2025, when Fay Claassen presented Koosje with the Rabo So What's Next Talent Award during a performance at Amsterdam's Bitterzoet. The two musicians performed a pair of spontaneous duets, discovering an immediate musical connection that inspired them to develop a complete concert programme together.

Two distinctive voices, one musical connection

Fay Claassen is one of the Netherlands' most respected jazz vocalists, with four Edison Jazz Awards and an international career spanning three decades. Known for her expressive voice and adventurous interpretations, she has performed at major festivals including North Sea Jazz and collaborated with leading jazz musicians and orchestras.

Koosje represents a younger generation of Dutch singer-songwriters, combining neo-soul, folk, R&B and jazz harmonies into a distinctive contemporary sound. A multi-instrumentalist and composer, she has released two albums and graduated with distinction from the Royal Conservatoire in The Hague.

From Judy Garland to The Beatles

Their joint programme takes its name from Get Happy!, the famous duet performed by Judy Garland and Barbra Streisand. Alongside their interpretation of that classic, Claassen and Koosje explore personal arrangements of familiar songs, including music by The Beatles, as well as selections from their own repertoires.

The singers are accompanied by pianist Karel Boehlee, whose collaborations include Toots Thielemans and Philip Catherine, and guitarist Aaron Hanenberg, who has worked with artists including Akwasi and Joya Mooi.

Expect a concert that moves between delicate vocal harmonies and powerful, expressive performances, with improvisation, humour and musical surprises connecting the different styles.
