In 1882 he was a co-founder of the , which he and 53 other musicians formed out of the former Bilse's Band. Along with his job as a solo flutist, he took over more and more conductor's assignments and conducted over 8 summers one of the orchestra's two daily concerts in Scheveningen.
In 1893 Andersen was forced to resign his job because of a paralysis in his tongue and travelled then back to Copenhagen where he was employed as a composer.
