Recorded in 1971, shortly after he departed Cadet where he served as a house sideman-playing on dozens of records and a prefferred guitarist for Curtis Mayfield and Jerry Butler, Phil Upchurch headed for the West Coast and Blue Thumb Records. Produced by Tommy LiPuma, Upchurch's Darkness, Darkness is his quintessential (double) album, full of laid-back funky grooves, elegant, mind-blowing guitar work, elegant string and horn arrangements, and fine Fender Rhodes work from Donny Hathaway with legendary session bassist Chuck Rainey and smooth jazz piano great Joe Sample in the house. Upchurch effortlessly walks the line where jazz, blues, rock, soul, and funk fold into one another, yet he never gives quarter in the process.
