For a while there, duo Ross Wariner and Cody Uhler — plus the grip of locals they employed under the Kindercastle umbrella — comprised one of the most promising young outfits in the local rock scene. Then they up and called it quits. Wariner continued playing with roughly the same aforementioned grip of performers — strings, horns, rhythm section, the whole nine yards — under the moniker Uncle Skeleton, even winning the third round of this year’s Road to Bonnaroo series at Mercy Lounge and thus securing a spot playing in Manchester next month. (Uncle Skeleton will be the very first outfit to play the whole shebang, as a matter of fact.) And then, when we all least expected it, Kindercastle announced their triumphant return, marking the occasion with the release of their second full-length album, Number B, via local label YK Records. Featuring much of the same funk-infused, kitchen-sink baroque pop and old-time crooning they were known for before their hiatus, Number B sports a handful of tracks that were also featured on 2009’s Dot to Dot to Dot EP. The brand-new numbers, however, feature the graceful electronic flourishes and string arrangements Wariner has made his trademark in Uncle Skeleton. Number B is a complex collection of co-dependent systems — a skeleton of familiar electronic pop topped with ethereal, alien flesh and subtle adornments. It’s ELO for computer nerds, or perhaps Depeche Mode for fans of ‘60s and ‘70s sunshine pop (Beach Boys, Harry Nilsson, et al.). Or maybe it’s something else altogether. See for yourself.
