The first time around I thought it must be the room or not a great mixer. The second time made me think this is a trend. If it is, its not a good one. I’m thinking this is borrowed from Hip Hop records use of 808 synth to make that really heavy low low end. Sheila E’s bass drum was definitely triggering a very low and loud tone. Unfortunately I wasn’t able to stand near the mix position in either case. Next time.
I won’t be going to many live shows if my fears are born out. Thanks for the replies.
