Workshops? What did you have in mind? A one time workshop? Covering what aspect of Music? Performance opportunities? I know of several factories & business locally & in other cities where I've lived which have ongoing Music ensembles such as choirs-Hymns/Spirituals/Classic literature; Jazz Bands, Traditional Music Ensembles-Bluegrass, Folk, Blues, etc. Sometimes the type of Music depends upon the region of the country/world. The employees are a combination of white & blue collar. It is very good for the folks to see each other in a completely different aspect such as Music. It gives someone a new understanding-& often newfound respect- of another when seeing their Musical talents & achievements.
