Every so often, Late Night With Jimmy Fallon will devote an entire week of musical performances to a single legendary artist. This week is Pearl Jam week. In a lot of ways, that’s a total no-brainer; the band just released Lightning Bolt, their 10th album, and they also just celebrated the 20th anniversary of their landmark sophomore LP Vs. Still: Smart choice! Pearl Jam has a whole lot of prominent admirers, and a whole lot of songs worthy of covering, both canonical classics and relative obscurities. Last night, we got the latter. Chris Cornell, the Soundgarden frontman and longtime Pearl Jam buddy, linked up with Seth and Scott Avett, of the insanely popular neo-bluegrass vest-folkers the Avett Brothers, to cover Pearl Jam’s 1992 song “Footsteps.” The track was the B-side to the “Jeremy” single, and Cornell sang a different version of it, entitled “Times Of Trouble,” on the Temple Of The Dog album. The performance, rootsy and acoustic and harmonica-laced, was a pretty thing indeed. Watch the performance and a bonus interview with Cornell talking about Pearl Jam below.

Tonight, we get Fleet Foxes frontman Robin Pecknold covering “Corduroy,” which should be just awesome.
