After spending a decade establishing themselves as a top-tier '60s revival band, forging a sound that lived in the sweet spot where jangling folk-rock, melancholy guitar pop, and fuzzy psychedelia meet, the Young Sinclairs dropped out of sight for a few years beginning in 2015. When they returned in 2019 with their third album, Out of the Box, things had changed. The band weren't just mining that fertile, if a little narrow, plot of ground anymore; this time they cast a wider net and rope in all kinds of new sonic influences. Along with a healthy dose of songs that have the same look and feel of previous works, there are some huge stylistic swings including soul retro enough to make the Dap-Kings nervous ("Get Along [I Hope That You Do]"), candy-sweet soft rock ("Birthday Card"), late-period Spacemen 3-inspired drone psych ("Come On Now [Give You All My Love]"), reverb-heavy modern chillwave ("Leviathan"), and most surprisingly, a strong dose of early-'90s-style baggy psychedelia. Whether slow and dreamlike, as on the luxe album opener "Drifting Haze," pulsing and electronic ("In the Room"), or a little funky, like the insistent groover "Same Old Now," Samuel J. Lunsford and the band do a fine job of capturing both the sound and spirit of that brief moment when baggy was on the rise. Along with the more experimental songs, they sound note perfect when digging into more traditional '60s sounds; "Action Movies" is a bouncy action pop song with hooky guitar parts and the kind of chorus that gets stuck deep in the brain, "Truth Can't Be Tried" is a lovely Zombies-style ballad, and "Stay All Night" is a peppy garage blues that wouldn't sound out of place on the first Chesterfield Kings album. While the juxtaposition of half old-school Sinclairs tracks and half new-school genre exercises can be a little jarring at times -- the retro-soul track sounds out of place and the Spacemen 3 pastiche is a little too on the nose -- it's hard to fault the band for trying new things, especially when they sound like they had a great time making the album. It will be interesting to see which of the new sonic avenues they pursue in the future or if they revert to being a known commodity. Out of the Box positions them well for either path.
