In his 2007 book Love Is a Mixtape, rock critic Rob Sheffield explained why he considers the synth-pop duo to be his favorite musical pairing. To him, the classic form works as a symbiotic relationship. The shy producer, lurking in darkness behind the synth, is too reserved to sing songs himself. He needs the human flair of a larger-than-life vocalist, who in turn needs a โ€œcerebro-electro henchmanโ€ to deliver sparkling sounds. Together, they electrify the audience and achieve stardom. Durham duo Sylvan Esso built its career on this approach. With the wry single debut of โ€œHey Mamiโ€ in 2013, Sylvan Esso emerged as a genre-bending folk-electro curiosity, odd and lyrically incisive and inextricably linked to each otherโ€™s talents.

Producer Nick Sanbornโ€™s scruffy IDM beats proved a nice minimalist foil for vocalist and onetime Mountain Man member Amelia Meathโ€™s wispy delivery. Together, they shot to national popularity, countless retail playlists, and engendered fevered anticipation for their second release. Yet as we also know, indie fame is famously fickle. They could have easily become a one-album wonder, a โ€œformer buzz bandโ€ punch line. Fortunately, that isnโ€™t what happened.A better track-for-track album than the duoโ€™s self-titled 2014 LP, What Now proves Sylvan Esso has plenty of charisma and interesting musical ideas left in the can. As always, the musicโ€™s breezy sing-song aesthetic belies its subversion, cloaking acidic commentary in easily digestible pop nuggets. Take first single โ€œRadio,โ€ which, in classic Top 40 form, clocks in at a smooth 3:30. Under the songโ€™s bouncy glitch-pop exterior, it seethes with barbed observations (โ€œNow donโ€™t you look good sucking American dickโ€) about our current attention economy and PR-driven music landscape. While itโ€™s far from the first song to try the โ€œwokeโ€ radio single conceit, itโ€™s a smart, memorable attempt.

Elsewhere, What Now eschews social commentary to search for specific feelings and memories. โ€œThe Glowโ€ is a twitchy, nostalgic ode to the pleasures of music and companionship, both publically and privately. Specifically, Meath recalls dreamy memories of listening to The Microphones, whose vocalist Phil Elverum is mentioned in the lyrics.In general, What Now aims for a bigger electronic sound, and while Sylvan Esso never quite reaches gaudy big-room EDM, itโ€™s a moderate turn away from the bandโ€™s floaty, folky side. Thereโ€™s still some classic Sylvan slow jams, like โ€œRewind,โ€ but some of these songs might be hard to play in the background of say, a coffee shop. Sanborn and Meath have expanded their creative palettes, and they look to be settling in for a long, steady ride. David Ford Smith
