Here's a first: Steelpans at the Tiny Desk. It's true. Nearly a thousand performances into the series and the instrument has never been featured, until now. While the two bowls look shiny and new in this Jonathan Scales Fourchestra set, they were once authentic oil barrels, pounded, finished and tuned for bandleader, Jonathan Scales. But instrumentation and singularity aside, Scales' virtuosity, energy and connection to his bandmates wowed the NPR crowd, many of whom had never heard this music before.
