"Morphing from their roots in gospel and doo-wop through funk, rock and then, finally, into slow-jam R&B, The Isley Brothers remain one of the most fascinating groups of all time. Yet, somehow, they're also perennially unappreciated - underrated, almost; certainly taken for granted in a way that James Brown or P-Funk are not. The RCA Victor And T-Neck Album Masters (1959-1983) will go a long way towards redressing that balance. It contains, simply, some of the most life-affirming music ever recorded: Ron Isley's keening yelp offering strength and sensitivity as it's supported by brothers Rudolph and Kelly. Their church background is evident on their 1959 debut album, Shout!, while their vocal blend remains strong right up to the bump'n'grind of 1983's Between The Sheets".
