[1] In 1477, Lannoy, along with Jean Japart, Johannes Martini, and Loyset Compère, was given a pass to leave Milan following the murder of Duke Galeazzo Maria Sforza.
The singing group at the chapel had been one of the most distinguished in Europe, and the compositional style which developed there in the 1470s was widely influential: for example the motet-chanson was probably a Milanese invention.
A line in Guillaume Crétin's elegy on the death of Johannes Ockeghem (6 February 1497) indicates that Lannoy had died by then.
Only two compositions are definitely attributed to Lannoy, both secular songs: Cela sans plus and Adieu natuerlic leven mijn.
It is given to "lanoy" in the source, and the style is consistent both with Lannoy's songs and with that of other composers working at Milan.
