Amazing performance by Trevor Oswalt in which you need to hear it to believe it.
Under the moniker of East Forest, Portland’s Trevor Oswalt weaves ethereal soundscapes from vintage keys, intimate vocals and original field recordings. His sonic architecture reflects motifs of nature and the inner spiritual landscape, and experiments with elements of pop and contemporary themes. The wide-ranging textural sound has been called “blissful” by National Public Radio and has been compared to Sigur Ros, Bon Iver and Explosions in the Sky. He has collaborated with Deepak Chopra, shared stages with artists including Moby, Sarah Neufeld and Random Rab, and composed and licensed music for TV, film, theatre, apps, video games and dance companies.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

#GlennGreenwald was one of the first #reporters to see — and #write about — the #EdwardSnowden #files, with their #revelations about the #UnitedStates' extensive #surveillance of #private #citizens. In this searing #talk, Greenwald makes the case for why you need to care about #privacy, even if you’re “not doing anything you need to hide."
