Steve Harris is, undoubtedly, one of the driving forces behind Iron Maiden. This song is a great showcase of his style, tone and technique (he also uses flatwound strings). I have embedded an extra video for the isolated bass.
If you like the isolated bass track feature, please drop a comment so I'll remember to do it more often.
