Kirk Hammett's guitar solo on Wherever I May Roam showcases his ability to blend the Eastern scales and exotic modalities he incorporated into Metallica's Black Album material with his pentatonic blues-metal vocabulary. The solo rises from the song's hypnotic, road-trip groove and achieves a sense of wide-open space that matches the lyrical theme of restless wandering. The Black Album was recorded with producer Bob Rock and remains Metallica's best-selling record.
