Alligator Records rightfully won raves for this series, arguably the greatest modern blues collections out there. Volume four features Detroit Junior ("Some Nerve," "I Got Money"), Luther "Guitar Junior" Johnson ("Somebody Have Mercy," "Look What You Done"), Big Leon Brooks ("Country Boy," "My Life Ain't the Same"), Andrew Brown ("Two Years"), Queen Sylvia Embry ("Going Upstairs")...19 tracks, many maddeningly hard to find!
