That being said, the collection's curator, guitarist Kim Thayil, has still managed to unearth a few nuggets. Early out-of-print efforts like "Toy Box" and Badmotorfinger-era B-side "Cold Bitch" capture the quintessential Soundgarden groove, while the straight-ahead No Alternative cut "Show Me" and a jaunty cover of the Rolling Stones' "Stray Cat Blues" showcase the band's pop sensibilities. While it's convenient to have so many of the original rarities in one place (namely, disc one), too few of the covers that comprise the second disc really live up to Soundgarden's legacy. Still, their take on Black Sabbath's "Into the Void" is positively crushing (no duh), and the silly set closers from Louder Than Live, "Earache My Eye" and "Big Bottom," are worth revisiting.
Highlights from the third disc are limited to the shape shifting Down on the Upside-era B-side "Karaoke" and the brilliant doom-metal original version of "Fell on Black Days" ("Black Days III," which, again, was included in the Superunknown reissue). With a remastered Ultramega OK on the way and an inevitable 25th anniversary edition for Badmotorfinger in 2016 — both of which will likely include their own bonus tracks — Echo of Miles just seems like a holiday season stopgap for superfans who've already worn out all five discs of the Superunknown box set.
