I really like these posters for Billy Strings’ Streaming Strings concert series. Halfhazard Press from Bloomington, Illinois is producing a series of very limited edition prints for each show that you have to purchase the concert stream to be eligible to purchase. I think it is a great idea, marketing-wise to do these types of promotions in order for musicians as well as concert poster designer/printers to continue to try to make a living.
By the way - Billy Strings has the best merch out there of anybody.
