Glen Campbell, “The Essential Glen Campbell, Volume Two,” Capitol Nashville. **

Though Campbell’s name and voice have not disappeared in any way close to the extent of James’, there is far less focus on him in either country or pop circles than you’d expect for someone who enjoyed such success in the ‘60s and ‘70s, from the many Jimmy Webb hits (including “By the Time I Get to Phoenix”) through “Southern Nights.” While an occasionally pleasing song stylist (“Gentle on My Mind” here), Campbell too often is simply a colorless singer. You can quickly see why his lackluster versions of Joe South’s “Don’t It Make You Want to Go Home” and Tom Paxton’s “The Last Thing on My Mind” were not previously released. For fan loyalists only.
