Howlin' Wolf is a classic blues artist.He has influenced everyonefrom Page,Clapton,and the Rolling stones.Especially in Led Zeppelin you can hear the references clear and sound.This set includes legendary sessions with special guest stars.The remaster versions are outstanding.These songs have been long out of print,only for collectors.This is essential for any serious blues fan.As we know there is no Rock and Roll without the blues.Next to Robert Johnson's "King of the Delta Blues",this is a must have disc set.Blues fan -Ant
