The University of Central Arkansas wraps up this season's "Nostalgia Series" with a night of squeaky-clean AM radio classics from The Buckinghams and Blood, Sweat & Tears, two mainstay bands on golden oldie compilations, state fairs and record store bargain bins. Don't take that as a slam, though. The Buckinghams' breakthough song, "Kind of a Drag," is a canonical piece of late '60s white-boy pop and only suffers from being too tight. That's a great problem to have. Likewise, Blood, Sweat & Tears' early '70s fusion of big-band, jazz and rock on display in their self-titled album is undeniably great, even beating out "Abbey Road" and "At San Quentin" for the Grammy album of the year award back when the honor was an honor.
