Stevie Wonder started one of the greatest album runs of all time with "Music of My Mind" and culminated in "Songs in the Key of Life", a run of five amazing albums. Sat in the middle of this was "Innervisions", it builds upon the pervious two albums and manages to achieve a greater balance in overall subject and sound. Themes on social commentary, love, spirituality are here like many of the album's in this run, but somehow everything seems tighter, more resolved here.
