See Temple of the Dog Cover Mad Season's 'River of Deceit' at Second Gig

Supergroup of Soundgarden and Pearl Jam members also stage live debut of 'Superunknown' outtake "Missing"

Temple of the Dog paid tribute to another Seattle supergroup with a cover of Mad Season's "River of Deceit" and debuted "Missing" Saturday night.

Temple of the Dog – the reunited grunge supergroup featuring members of Pearl Jam and Soundgarden – paid tribute to another Seattle supergroup Saturday night as they covered Mad Season's "River of Deceit."

Pearl Jam guitarist Mike McCready is the common thread between the two bands, playing that role in both the Chris Cornell- and Layne Staley-led projects.

However, Cornell has plenty of experience filling in for the Alice in Chains singer as he first performed "River of Deceit" during a one-off Mad Season reunion in Seattle in January 2015. Since then, Cornell has covered the Above song as a solo artist upwards of 40 times over the past two years.

Temple of the Dog, onstage at Philadelphia's Tower Theatre for the second time in two nights, largely played the same covers-filled set list as their Friday night debut with two notable exceptions: "River of Deceit" and the live debut of "Missing," a Superunknown outtake that has appeared on bootlegs but was never formally released.

"We're gonna do a song that's never been released on anything, ever. This is the first time it's ever been performed by anybody, as far as I know," Cornell told the crowd. "This was part of a group of songs that I wrote were based on some song titles that Jeff [Ament] came up with when he was working on some set decoration. One of those song, the title was 'Seasons,' one of them was 'Spoonman,' and this one called 'Missing.'"

After some slight technical difficulties, the supergroup unleashed the unearthed track:

Temple of the Dog's 25th anniversary reunion tour continues Monday at New York's Madison Square Garden.
