It’s taken roughly six years for Berlin singer Clara Hill to pull together her fourth album, Walk the Distance. As it stands, the set sounds assembled from a variety of sessions recorded over the years. Collaborating with Schneider TM, Hanno Leichtmann, and Kalle Kalima, among others, Hill wanders the musical countryside, working with a demo-ish dance track in “Dripstone Cave,” an orchestrated chamber-folk direction in “Konkav,” an ambient but pressurized tonal atmosphere in “Insomnia,” and even shades of ‘90s shoegaze and indie rock on “Lost Winter.” Hill often composed and recorded the basic tracks at home, leaving room for her collaborators to add accompaniments at a later date. Hill says she left “small inaccuracies” in her performances to keep the results somewhat homespun, as opposed to the clinical comfort of a computer’s perfection. This shouldn’t be taken as an admission of amateurism but rather an effort to create music that benefits from a human touch. The title track and the nine-minute mystery of “Glacial Moraine” are excellent examples of this.
