I shared that sentiment for most of my life...we only did covers in our own style, if we did them at all...one cover per 45 minutes of set time max.
That was back when there was a healthy, local, original scene around here.
Now it’s not the same locally. The usual dives fire us for playing too much original material. It doesn’t matter how well it goes over...usually...there have been a few exceptions over the last few years where we get away with requests if the dance floor keeps moving, and the booze keeps selling.
That said, we play most of our covers in our own style. Usually really heavy, and energetic.
Some covers though...they come out fairly accurately, for me. For example; I recently re-learned Pink Floyd’s “Mother” for an internet collaboration. I feel like I did it fairly faithfully, and that seemed the right course of action for me.
Meanwhile, my band does Pink Floyd’s “The Machine”...you’d hardly recognize some of it. It usually works well for us live too.
(Come to find out our version is probably closer to the version by Shadowsfall, than to Floyd. I don’t think the Shadowsfall version was released until after we did our version, as a request by a rehearsal guest...on a whim...none of us had actually played it before, except me...for an old girlfriend...acoustically. So I knew the basic chord structure, and lyrics.)
So, I’m the original spirit of this thread...make them mine...if I feel it’s a tasteful thing to do.
