On a sunny day in October 2017, Shyam Nepali was walking along the Charles River and noticed Charlie Giargiari playing guitar on a bench by a waterfall. Shyam quickly ran home and got his Nepalese sarangi for an impromptu improvisational jam. And so began 40 Million Feet. 40 Million Feet is the approximate distance from Boston to Kathmandu, Nepal. NPR’s Tiny Desk Concerts said, “The blend between the unlikely pair of instruments is something magical, effortlessly capturing the essence of two different music worlds.”

It’s part of the Eliot Schoolyard Concert Series, featuring music from jazz to R&B to folk and funk, harp to steel pan, every Sunday at 4 from now through September, curated by pianist/composer Brian Friedland (who initiated the series), Hoopla Productions (which has produced JP Porchfest), and Oompa & The Record Co. (which just re-opened its renovated recording studios in the South End).
