We fear that perfect performances sometimes slip past you in all the ephemera (horrors!) posted on The Lefort Report.  So just to make sure this one didn’t get entirely glossed over, we thought we’d draw your attention again to this cover by Elvis Costello and The Roots of Springsteen’s Brilliant Disguise off of his less-than-brilliant Tunnel of Love album. We initially posted it as a part of Jimmy Fallon’s Springsteen Week in early March, and it took us nearly a month of replay to realize the bountiful brilliance.  Costello and The Roots pare back the song to its soulful roots (if you will) and prove once again that so much can be added by subtraction.   With Questlove’s divine drumming, perfect metronomic piano and harmony vocals in support, Costello (looking rather leprechaun-ish in his green hat) adds beaming bass and renders his usual soulful vocal delivery.  Via the dynamic arrangement, Costello sends his standard striking song interpretation.  And when the bass and piano drop out at 4:01, only to kick in full-on at 5:08, all is right with the musical world.   Please stop us before we replay again!
