Perhaps Mr. Wonder's magnum opus. It's interesting to read that Wonder had plans to quit the music industry leading up to this album. The creative bug must've got him good, as he eventually conjured up the inspiration to release a double album with all sorts of talent helping out; such as George Benson, Herbie Hancock, and Michael Sembello among many others. So what makes this particular album among Stevie Wonder's best? Well, the aforementioned talent involved certainly helps, but everything in the recording and production just sounds even more refined. The fusion of R&B, soul, jazz, funk is adeptly showcased here, along with the usual passion and vigor from Wonder. All while singing about subjects ranging from love, faith, social justice & equality. This honestly would've been a fine swan song for Wonder if he so desired, but the man just couldn't stop grinding away and creating more records. He's a musician through and through. "Songs in the Key of Life" will always be present whenever we need it.
