Amy Helm said she felt like these trying times needed music that was hopeful and uplifting, and her new album "This Too Shall Light" includes songs chosen for their affirming aura and communal spirit. Helm's new album is slated for a September 21 release, but before that she's scheduled to perform on Saturday's edition of this weekend's Festival at The Farm, which is being held Saturday and Sunday at the Prowse Farm in Canton.
