With his eponymous 2011 debut — a sort-of minimal techno analogue to Bruce Springsteen’s nocturnal “Nebraska” — 22-year-old James Blake asserted himself like, well, a boss. On follow-up “Overgrown,” the U.K. singer-songwriter-engineer fleshes out his down-tempo soundscapes and young-man-scorned vocals with ethereal piano, chasmlike bass, found-object percussion and appearances from producer Brian Eno and rapper RZA. Although Blake has visited Seattle three times in 18 months, Tuesday’s Neptune show might represent fans’ last opportunity for an intimate moment with the wiry wunderkind. 8 p.m. Tuesday at the Neptune Theatre; $30 (877-784-4849 or
