There is no such thing as a good drum solo.
Drum solo's ruin gigs.
All the way through the 70's every band in the world thought it was a great idea to do drum solos and thats when you went to the bog.
Neil Pearts recent drum solos can be interesting for about 2 minutes and a guy called Jon Hiseman who was with a band called Colloseum had me mesmerized in the 70's but only because he was juggling.
I allow my drummer a one minute solo at the end of Led Zeppelin Rock And Roll - anymore I turn him down on the PA.
There is one local band who halfway through the second set their drummer does a 10 minute solo and they've never worked out why everybody walks out.
He's a brilliant drummer but everybody knows drum solos should be put in Room 101.
