Philharmonic Brass

I do not have sufficient reliable knowledge about an organization called 'Philharmonic Brass' to provide a detailed description. There may be multiple ensembles or groups with similar names in different locations. Without specific location details or unique identifiers, it's not possible to ascertain which specific ensemble it refers to, if any. It's also possible that this could refer to a section within a larger philharmonic orchestra, rather than an independent ensemble. If more specific information or context is provided, such as the city or country, it might help in identifying the correct organization.
