This week circles back one final time to AmericanaFest 2018, where a global community dedicated to American roots music gathered and networked and listened to some of the world’s best music. Amy Helm, out solo after a decade with Olabelle and working with her late great father Levon, is an exceptional singer with the new album This Too Shall Light. Veteran alt-country and bluegrass singer songwriter Robbie Fulks showcased his new rollicking boogie woogie rock and roll project with pianist and singer Linda Gail Lewis, Jerry Lee’s sister. Their duo album is called Wild Wild Wild. And rounding out the hour is emerging Canadian folk artist Kaia Kater.  She’s on a remarkable journey of identity and creativity, and she is newly signed to the iconic Smithsonian Folkways record label. Her album Grenades is out in a matter of days.
