1...download a video of a metal bassist(like Rob Trujillo etc.) doing the spider technique(for free). 2...download songs of black/Viking metal acts Bathory,Celtic Frost,At the gates,Burzum etc.I can't get their music anywhere(also for free). 3...download recordings (if they do exist,that is)of bands Steve Harris was in before Maiden.(needless to say,for free). Thanks.
