On this day in music history: September 13, 1985 – “In Square Circle”, the twentieth studio album by Stevie Wonder is released. Produced by Stevie Wonder, it is recorded at Wonderland Studios in Los Angeles, CA from Mid 1983 – Mid 1985. Recorded over a two and a half year period, it is Wonder’s first full album of new material since “Hotter Than July” five years before. Wonder actually takes time away from his work on the album to record the soundtrack for the comedy “The Woman In Red” as well as embarking on an extensive tour of Europe during the Spring and Summer of 1984. Besides Wonderlove, the band of musicians he has been working with for much of the last decade, Wonder also invites other musician friends such as guitarist Earl Klugh, and vocalists Luther Vandross, Deniece Williams, Philip Bailey and Syreeta Wright to perform on the album. It spins off four hit singles including “Part Time Lover” (#1 Pop, R&B, Dance, & AC), “Go Home” (#2 R&B,#10 Pop), and “Overjoyed” (#8 R&B, #24 Pop). Stevie also wins a Grammy Award (his thirteenth) for the album for Best Male R&B Vocal Performance in 1986. The original vinyl LP comes in a glossy gate fold jacket with embossing on the front and back cover, also including an eight page color booklet with photos and lyrics. “In Square Circle” spends twelve weeks at number one on the Billboard R&B album chart, peaking at number five on the Top 200, and is certified 2x Platinum in the US by the RIAA.
