Rolling Stone - 1/7/71, p.48
"...Any of the 12 songs on [this album] holds more creative singing than you're likely to find in another performer's entire body of work...there's not one bad cut on the LP..."
As you listen to this album, you will inevitably find yourself lamenting the devastating shortage of hours in a day in which to continue grooving. 1970's SIGNED, SEALED AND DELIVERED marks another turning point for Mr. Wonder as his lyrics grow more world-conscious and the music gets indubitably funkier. Swift, dynamic bass-playing, deep clavichord and head-nodding riffs are just some of the elements which drive the new sound. Those who cherish his more sugary Motown nuggets of the '60s needn't fear, though--they too continue to claim a space.
The title track may well place you unwittingly en marche to the door of your sweetie. The high-stepping horn lines and husky rhythm section lay the foundation for a swinging vocal delivery laced with sitar. Stevie later holds church of the grooviest order on "Heaven Help Us All," raising his good will towards humanity to a thunderous crown of horns and choir. The thrilling "Sugar" and a lively rendition of "We Can Work It Out" display his highly effective technique of vocal layering through overdubs. This album is full of fine R&B with many tasty surprises.
