I’m guilty of it myself, when I was younger all I wanted to do was blaze scales up and down the neck. It looks and sounds cool at first, it even has its uses…but then you hear the “same” solos from Yngwie Malmsteen that he played 10-20 years ago on his most recent releases or you see this:
At some point, it just isn’t music anymore. Can you even tell that it’s ‘Flight of the Bumblebee’ anymore, at the later tempos?? It becomes noise/noisy.
Used correctly, speed can be tasteful. Toss in some bends, vibrato, slides, etc., but please, PLEASE, don’t dedicate all of your team to trying to play quickly. Dedicate SOME time to it, an hour a day where you alternate pick scales to a metronome, but then go and play some blues, or something similar.
