The debut full-length album by Bay Area-based songwriter Maria BC, Hyaline accesses snapshots of grief, anxiety and wonder through a miscellany of specters. Their classically trained mezzo-soprano soars over raw, ethereal guitars; audio samples dapple across minimal percussion; organ, played by Maria BC's dad at his church in Ohio, settle alongside tender, transformative harmonies. Mixing together different sessions, tracks recorded directly into their phone and samples collected over the years, Maria BC likens Hyaline to a "sonic collage."
