This is the first santana record I ever liked and bought in the 70s.The sound gets better each time you play this record and there is nobody(singer,band etc) to compare with this great santana line up which provided the world with this great gift of music.All songs are great song-wise and rock-wise and trust me when I say this is pure art!The true magic in this album and band is the unique combination of different types of music(afro music,latin american music and western rock music) all coming together as one blended in harmony under the stewardship of Carlos Santana producing an awe inspiring sound that has stood the test of time ."Mother's Daughter","Black magic Woman","samba pati" "Se Nkabo" are all timeless classics that Carlos himself has failed to beat to date.This ,without a doubt,is the greatest rock album ever.
