I think we can all fully understand artists such as Dylan wanting to monetize back catalogues in their twilight years when revenues from streaming are so pitiful, to protect their dependents. Apparently David Crosby and Joni Mitchell are very likely to follow suit. I think archive releases will probably proceed as they have been doing. With the artist relinquishing control will we see more? Who knows. The labels don't really have a great history of making the best decisions though do they?
