Saxophonist Ronnie Laws, the younger brother of flutist Hubert Laws, started his career in the band of trumpeter Hugh Masekela. In 1972, Laws joined R+B/funk legends Earth, Wind + Fire and played on their album Last Days and Time before moving on to his solo career.
During 1975, Laws teamed up with jazz trumpeter Donald Byrd, known as one of the only jazz musicians from the Bebop era who also explored funk and soul while remaining primarily in the jazz genre. According to AllAboutJazz.com, with Byrd’s assistance, Laws “soon signed his first recording contract with Blue Note records, resulting in the impressive debut album Pressure Sensitive (1975)…The release rapidly emerged to become the longest-selling album,” to date, in the 42-year history of the storied record label, reaching #25 on the Billboard Soul chart and gaining extraordinarily broad rotation across R&B, Soul, Jazz, and Rock radio stations.
The track is built around slightly off-kilter tuning, but it’s closest to F# minor. What’s definitely clear is the bridge’s departure from the regular key, as well as from the otherwise all-pervasive groove, from 3:01 – 3:28.
