The Innocence Mission explores grief, longing, and hope in their new album, “My Room in the Trees.” Karen Peris’ soft voice glides over the songs, which recount days spent with her children, the blessing of morning light, and the “summer of a hard year.” This is another lyrical masterpiece from the beloved band, whose quiet melodies hang on rich words: “Everything that has been broken you’ll mend/throughout the morning of one day . . . and we’ll shout, shout for joy.” (Badman Recording)
