Wright's second album, which includes performances by guitarist Bill Frisell and singer Toshi Reagon, has spent five of the six weeks since its release at number one.
Hardcastle's album dropped to number four in its second week, with Bobby Caldwell's Perfect Island Nights at number two and Kenny G's At Last... The Duets Album at number three.
The jazz chart was barely changed from last week, with Michael Bubl_'s It's Time at number one for the 23rd time. Keith Jarrett's Radiance, which dropped off the chart earlier this month, returned at number 16.
