The Washington City Paper thought that "the scrupulously tailored verse-chorus cadence of Glimmer's anthems feels so immediately familiar that Salem could probably make a mint ghost-writing for Tom Petty."[13] The Austin Chronicle stated that "Glimmer is loaded with big guitars—chunky, Seventies-style arena-rock rhythms (think Joe Perry sans high-dollar production) with indie tones and guitar-noodling solos."[14] The Tampa Tribune wrote: "Tom Petty with indie credibility for those hipsters who are too embarrassed to admit that Damn the Torpedoes rocks."[12]
Stewart Lee, of The Sunday Times, declared that "beautiful, compelling, nerve-shattering lead-guitar lines snake and spiral over clean and uncluttered rhythm parts, never resorting to simple effects-pedal overload"; Lee later listed Glimmer as the best album of 1996.[15][16] The St. Paul Pioneer Press thought that "Salem's tough/tender tunes, guitar wizardry and no-frills, all-thrills band just might set you on an endless road trip."[17] The Boston Herald deemed it "a screamer of an album that works the intersection of heartland rock 'n' roll and guitar-driven alternative rock."[10] The Press-Telegram considered Glimmer to be the fifth best album of 1996.[18]
AllMusic wrote that Salem's "serious but not humorless lyrics have an almost novelistic detail to them, especially on the haunting 'Chemical Night Train', and the band ... rocks throughout."[9]
