The SkyTracks Mixer is a new feature of this website released in the Summer of 2020 which allows you access to a special webpage with a MIXABLE Multi-Track player of all of the recorded parts of the demo for this arrangement. You will receive a link to this page along with a password, both of which you can share with your students so they can remotely access this versatile new learning tool.

For those who love Imogen Heap's "Hide and Seek", this piece captures a similar sound and emotional push. Vienna Teng's composition for herself with vocoder is a protest against government surveillance and corporate dominance, and it has a wide dynamic range and a powerful effect.
