If somebody chose to buy a big BassDrum - put the Set down at the staircase and practise on triplets including Bass-Drum......I think this are good ideas.
But if someone starts heavy drinking for achieving Bonham-Drum-Level, it's for sure the wrong way.
I think, it's a tragedy how this ended up. With alcohol every playing becomes bad without exception. Even John.
Yes, I agree, I watch all the shows about bands and members in bands how either drugs or alcohol consumed them during fame. Then after they get cleaned up (providing they lived through it) they go back into music but its never the same the second time around.
