What a comeback!  It was almost 30 years earlier when "Abraxas" hit number one on the charts and stayed there for weeks.  Santana's previous mega successful album that spawned the singles, "Oye Como Va" and "Black Magic Woman" but has become a classic rock classic also showed Carlos depending upon the work of others to get ahead.  Both tracks were covers and in the case of "Black Magic Woman" had the approval of the composer, Fleetwood Mac's Peter Green who was actively involved in the album but the other tracks like "Samba Pa Ti" were originals that were pretty good as well.
