Mac Mccaughan Manages To Be Extremely Prolific Yet Maintain A High Level Of Quality, And On I Hope Your Heart Is Not Brittle He Created An Idiosyncratic Masterpiece. The Guitar Twangs Out Pretty But Dissonant Melodies While Mccaughan Sings Oblique Lyrics Deep In The Mix. His Voice Is Nasal And Slightly Flat, But Somehow He Manages To Evoke Strong Feelings In Material Like "Gutter" And "The Main Thing."
