Led Zeppelin - II
Henry's request (my 9-year-old.) I remember buying this at Chesterfield Mall in St. Louis after swim practice one night and I was probably 10 years old (79ish). This is the same slab and still sounds great for oil crisis thinness.
You all know this record. The real achievements here are "What Is And What Should Never Be" and "The Lemon Song." I have to wince when I hear "Whole Lotta Love" but somehow that song still holds up when you hear it with vinyl crackles and hum.
