Van Veen had played with Bos since 1897 in a duo for piano and violin and with Van Lier in a string quartet. The three men united in 1899 to form "Das Holländische Trio". They made their debut on April 28, 1899, in Berlin with a concert dedicated in its entirety to the works of . In the fall of 1899, they also made their debut in the Netherlands. In Berlin on December 4, 1899, the Dutch Trio performed during a fundraiser benefiting the cause of the
Boer during the
Second Boer War. The musical part of the event was very successful, according to critics, especially because of the Dutch Trio's performance of
Mozart´s piano trio nr.2 in G major K 496. On January 10, 1902, the "Trio Hollandais" made their debut in Paris, in the Nouvelle Societé Philharmonique, playing the
Piano Trio No. 3 by
Brahms and Mozart's piano trio mentioned earlier. The critic praised their uniform sound and faithful reproduction. In his memoirs, Bos recalls that the famous violinist
Joseph Joachim, Van Veen's teacher, wrote a very positive letter about the trio's concert in the hall of the
Berlin University of the Arts in March 1903. Joachim himself and
Emanuel Wirth were invited as guests to play with the Dutch Trio Brahms'
Piano quintet. In January 1904, "
Il trio olandese" visited
Venice resulting in two well-received concerts in
La Fenice. On March 16, 1906, the Dutch Trio performed in the Singakademie in Berlin together with the
mezzo-soprano Julia Culp and three other singers. The concert was dedicated to Beethoven´s arrangement of Welsh and
Scottish songs (such as
The Cottage Maid and
Faithful Johnnie). As an intermezzo, Beethoven´s
piano trio op. 70/2 was played. At a concert dedicated to the tenor Ludwig Wūllner, as part of his tour of 18 performances in the Netherlands with Coenraad Bos, the Dutch Trio played on October 31, 1906 for the first time in the
Concertgebouw. Together with the
Concertgebouworkest conducted by
Willem Mengelberg the
Triple concerto by Beethoven was performed.
De Tijd was full of praise about Bos but expressed doubts about the other two members of the ensemble. The acclaim endured in Berlin according to a review in 1908 that describes a very highly regarded trio that had been active for ten years. In particular, cellist Jacques Van Lier was commended. However, the solo capabilities of the other two musicians did not completely convince ''''. In March 1908, the Dutch Trio gave two concerts in the
Casino in Copenhagen that caused an uproar. After the first concert,
Politiken had written that Van Veen was a dilettante. Before starting the second concert, Van Veen insisted that the correspondent of the newspaper exit the hall before they would play even a single note. Van Veen gained support for this demand from the audience, forcing the reporter to leave. In the Winter of 1908/1909, Marcellus van Gool replaced pianist Bos who was traveling in the United States. Later in 1909, Van Veen left the trio to settle in the Hague. He was replaced by the German violinist
Hugo Heermann. The last mention of the Dutch Trio of Bos, Van Veen or Van Lier in a Dutch newspaper is on December 13, 1910. It was reported that a tour of the trio in Spain could not take place because Bos had broken his leg. The commitments in Spain were taken on by the newly formed Heermann-Van Lier String Quartet with Maxim Ronis (second violin) and Ernst Breest (viola), who traveled to Spain after their concerts in Vienna and Paris. == After 1910 ==
