Brass and glass? Those can't be lightweight, that's for sure.
There's a video (which is over 10 years old and quite low rez) of these exact drum on YouTube. Sadly the video quality robs you of any chance of hearing any sonic differences between these any any other drum you might have heard.
A little over 13 years ago, I came across a picture of Alan White (YES) playing what looked to be a set of glass and brass drums. Being a drum nerd, my curiosity got the best of me. Were these gimmicks, art, or perhaps something more? I became obsessed with finding out more... So
Sooner or later the perfect frequency will activate thst mother and it shatter int a million pieces. But no fear Gorilla glue can patch it right up but then it will be like any ply kit and a bunch of glue. Somebody always wants to break a glass ceiling. So I want mine made of diamond so it won’t shatter.
Uh huh shattered, uh huh shattered
Love and hope and sex and dreams
Are still surviving on the street
Look at me, I'm in tatters!…
