After fiddling with the R&B of the 1980s and ’90s to great commercial success on 2016’s 24K Magic, Bruno Mars has assigned himself a more challenging project: Silk Sonic, a fidelity-obsessed act in which he and onetime tour mate Anderson .Paak recreate the rhythm and blues of the ’70s. The duo sought out particular drum skins to better replicate the sounds of the studio during the heyday of Gamble and Huff, when those songwriter-producers polished soul music to an extravagant sheen. With period-specific instrumentation in place, the exuberant pop hitmaker and the acclaimed rapper-singer-drummer with underground cachet recorded as their ancestors did, with just one or two mics for the entire room of musicians … (the) splashy interplay between male vocalists is perhaps the record’s strongest selling point: there are virtually no male R&B vocal groups of note these days, though the power of layered harmonies is the catalyst for much of the genre’s finest records, most notably the entire body of work of Marvin Gaye.
… Co-written by the singularly talented Babyface, the (2021) album’s big ballad (‘Put On a Smile’) digs as deep emotionally as Mars and .Paak are willing to go on a project that keeps the stakes low by choosing humor over sincerity at just about every turn. (Guest star Bootsy) Collins’ rhyming intro mentions ‘begging in the rain,’ and the subject matter doesn’t stray far from the Temptations’ ‘I Wish It Would Rain’ or the Miracles’ ‘The Tracks of My Tears,’ perfect songs about trying to mask your busted heart. Structurally, ‘Put on a Smile’ teases massive catharsis with its first chorus that it smartly holds back until the second refrain, when the drums finally crescendo and Mars leaps to the top of his falsetto. The song is played entirely straight, as the level of emotion calls for.”
Starting in C# minor, the ballad’s vocals-forward mix showcases Mars’ powerhouse delivery during the first verse, then shifts to .Paak’s raspy, heartfelt technique in the second. At 2:55, a half-step key change takes effect, nestled on all sides between compound chords. Mars continues to ascend to the stratosphere from there, until the tune returns to earth with both singers’ voices moving in close harmony.
