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, theres a transcendent aura that surrounds these songs, mined in large part by Galen Clarks atmospheric keyboards and Micah Hummels elusive percussion." - American Songwriter
