In February of 2021, Anna collaborated with Portland musician friends Galen Clark and Micah Hummel to reimagine a collection of songs from previous releases as well as one from an album due out next year. The resulting project, 'Blue World,' is a sparse and winding exploration of loneliness and love played out on keys, percussion, and one quiet voice. "(Tivel) has a keen gift of observation, and indeed, each of these offerings capture specific scenarios that are visual, dramatic and apparently culled from real life situations. Still, there's a transcendent aura that surrounds these songs, mined in large part by Galen Clark's atmospheric keyboards and Micah Hummel's elusive percussion." - American Songwriter
