She has the freedom to do things like this, not only because of digital recording technology and the internet, but also because she has been an "independent artist" since 2013. A revolution has been taking place in the "music industry" over the past ten years, and it can seem very confusing. But it's also an environment where a proven and dedicated artist can find more possibilities to make the kind of music she wants at her own pace and with a deeper connection to the people who recognize its real value.
The easy access to media is used by many different people in different ways, not all of them constructive. But we can only be happy when an artist of Audrey's stature and capability uses diverse media platforms to share her creative process with us.
Seriously, follow Audrey Assad on Soundcloud (see the link below). She posts songs here that she calls "living room demos" -- they are only available streaming on Soundcloud (which is free). She also streams videos and studio music tracks on her YouTube channel. This is why we have to support our INDIE artists - they're doing this for something more than money (though, obviously, they need money, which is why we have to be more than just "fans" -- we have to be collaborators in a community united by a common appreciation of beauty).
