About collectionCB4
collectionCB4 is a YouTube channel run by Corentin Boissier, a composer who works in the post-romantic tonal tradition. The channel presents little-known tonal classical works from the 20th and 21st centuries, mostly as full-length recordings with static images and descriptions crediting performers and conductors. The channel has about 3,450 subscribers and roughly 1,978 median views per video, and it has not uploaded in over a year.
The audience is likely small and niche, made up of classical listeners and researchers of rare repertoire. Age and location estimates are rough. The website shows Boissier's CD releases with Toccata Classics, which the channel promotes through teasers.
Brands in classical music, concert promotion or audio gear may find the channel useful for targeted awareness. At an estimated $20 to $35 CPM, it costs more per view than typical paid ads at $10 to $30 CPM, so it suits brands that value a classical-literate audience over raw reach.
