Boasting only two out of five founders (Henry Fambrough and Bobbie Smith), Philly-by-way-of-Detroit’s legendary Spinners have, like most hallmark acts of the R&B oldies circuit, spent the better part of their near half-century-long career existing more as a brand than a band. But when that brand includes laying claim to the title of Definitive ‘70s Soul Outfit — distinguished by indelible, smoother-than-smooth Top 10s the likes of “I’ll Be Around,” “Could It Be I’m Falling in Love,” and their ranking take on The Four Seasons’ “Working My Way Back to You,” to name but a few — it’s no mystery why the band continues to endure as their own tributary institution. Sure, still-active contemporaries such as The Temptations and The Isley Brothers have equally influential canons to cull from. But with their sleek, funk-infused, richly orchestrated update on the pop-vocal sounds of ’60s soul, The Spinners (along with The O’Jays) led the pack during their heyday, when the seams of the Motown set were beginning to show amidst moves to Los Angeles and the loss of top-shelf songwriters. If that’s indeed an era you’re nostalgic for (and, really, how could it not be?), then look no further.
