His reputation as an organist seems to have been high; several writers in the early 1580s, such as La Croix du Maine and Jean Dorat, praised his playing.
While he is known to have written music for the organ, only one composition has survived: a four-part fantasia on the madrigal Ancor che col partire by Cipriano de Rore.
Indeed, this is exactly what happened to many of them, and in this respect La Grotte's chansons are like the later air de cour, which featured a voice accompanied by a lute.
In addition, he combined duple and triple rhythms in irregular patterns, following the declamation of the text, in the manner of the composers writing musique mesurée à l'antique, such as Claude Le Jeune.
Many of La Grotte's chansons were published again later in arrangements for voice and lute, as airs de cour, under the name of Adrian Le Roy, the famous French music printer.
