FOXBOROUGH - Leon Russell told the crowd at Showcase Live that his wife convinced him he needed to speak more during his shows, but Mrs. Russell was probably just trying to ensure that the legendary singer-songwriter and session musician actually took some time to breathe. Now in his late 60s, Russell clearly still loves to play, because he scarcely stopped once he got started Thursday night.
That perpetual forward motion - songs blended into one another mid-chord change, with jaw-dropping precision - lent the 90-minute set a thrilling momentum. With his long, white beard and sunglasses making him look like a cross between a wise old snowy owl and ZZ Top's Billy Gibbons, Russell gave the packed house a tour of some of classic rock's choicest moments. Some tunes were those he played a part in writing or recording - like the spicy "Delta Lady"; others - like the Rolling Stones' "Wild Horses," which he rode with a goosed tempo and swampy organ - were by artists he's jammed with.
