Re: Ian Mosley!
totally agree - he has a great and totally unique style. When I first started listening to Marillion, I first thought his clock was awful - it sounded like he was speeding up and slowing down. It took me a bit to realize though that he was actually doing a bunch of implied metric modulations with triplets and such. He's cooled off quite a bit over the last few albums, but the earlier Marillion albums were filled with quite a lot of adventurous drumming.
He's also the quintessential example of a guy who doesn't need fancy new gear to sound good. He still records and tours with the same power tom Artstar II kit he's had for like 20 years.
