As a lifelong radio listener and musician, I'm constantly inspired by the sounds around me. My son's funny jokes, my wife's lovely laugh and even our pug's gruff bark.
Personally, the same holds true for NPR's wide range of programs. Locally, I enjoy the sounds of WAMC 90.3 FM and WEXT 97.7 (a listener-supported music station of WHMT). These stations celebrate all sorts of sounds including local music, political news and much more.
My goal with this design was to capture the frequent "WOW!" moments I experience when I'm listening to one of the many awesome NPR programs. Keep up the great work, NPR!
