The MoFi Ultradisc Gold re-issue of Abraxas was disappointing, imo.
Guess I'm just spoiled having heard the original group several times at the Fillmore East.
As the late Bill Graham would proclaim on stage in his introduction to the band,
"Ladies and Gentlemen, the joyous sound of Santana!".
Something got lost in the transfer, or it just wasn't there on the original tapes, imo.
