A credit line printed on the back cover of Nourished by Time’s strangely sublime debut — “written, mixed, produced & recorded by Marcus Brown in his parents basement in Baltimore, MD” — tells us so much about how inventive music gets invented, or, more specifically, how visionary artists are capable of making highly original, artfully offbeat, hyper-evocative R&B jams in spaces that are hospitable, rent-free, within the broadcast radius of 92Q FM, and where the sun won’t shine.
