This is the trio's fourth album and the record that really broke them through to a more commercially successful level of metal masters such as Led Zeppelin and Black Sabbath. Rather than rushing headlong back into their typical hard, heavy, and overamplified approach, Grand Funk Railroad began expanding their production values. Most evident is the inclusion of strings on the album's title track, the acoustic opening on the disc's leadoff cut, "Sins a Good Man's Brother," as well as the comparatively mellow "Mean Mistreater." But the boys had far from gone soft. The majority of Closer to Home is filled with the same straight-ahead rock & roll that had composed their previous efforts. The driving tempo of Mel Schacher's viscous lead basslines on "Aimless Lady" and "Nothing Is the Same" adds a depth when contrasted to the soul-stirring and somewhat anthem-like "Get It Together." The laid-back and slinky "I Don't Have to Sing the Blues" also continues the trend of over-the-top decibel-shredding; however, instead of the excess force of other bands, such as MC5, Grand Funk Railroad are able to retain the often-elusive melodic element to their heavy compositions.
