Hey, it's Joe, and I want to tell you about something new from our fellow radiotopian, Rishi Kesheirwe.

Rishi Keshe is the host of Song Exploder, where he interviews musicians about their creative process.

He's also a musician himself, and he just released his first album in 15 years.

It's called In the Last Hour of Light.

The album is deeply personal, like a memoir in music form.

It's also the culmination of more than a decade of being in conversation with other artists.

You can see him on tour this spring and he'll be bringing the spirit of Song Exploder to the shows.

In addition to performing his songs, he'll talk about his work, his life, and what went into this album.

He'll be joined on stage by folks like actor Adam Scott, author Minjin Lee, and chef Samin Nossrat.

Go to SongExploder.net slash live for tickets to those shows and find in the last hour of light by Rishi Kesh Hirway in record stores and streaming platforms everywhere. Radiotopia
