Second floor isolation

[willrock]

Hey guys
I did a quick search through these forums for isolation but there are a ton of threads and I'm not sure which is the best advice.
I've recently rented a pre built studio on the second floor of a building with a cafe below. Were cool to record drums etc after hours so to speak but would like to expand our time available to record already.
What would be the best way to isolate our room from the cafe?
Would relaying/framing the floor, high stc insulation, floorboard then neoprene then some acoustic underpaying and a new layer of laminate be enough.
I'm wanting to cut like 90% of the sound out basically.
Advice or am I totally screwed.

The latter part of the last sentence is correct. Low frequency isolation is expensive and drums include bass drums. Beyond that is the question of if the current floor can support the weight of an effective isolating floor.

Don't know if you got your advice, but check out my own thread: What is the best Sound Proofing underlayment to put under Hard Wood floor
I also found that the rigorous key to sound proofing is mass. That means, if you could, 10 feet of insulation/gypsum/plywood/underlayment-rubber-treament/plywood,etc..would be great and 99% of the time impossible.
So...depending on your cash flow: keep in mind Quiet Rock products, including Quiet Floor and Quiet Wood, I think it's called, as well as the other products posted in my thread and the installation process they so kindly post as .pdf files on their websites, to narrow down what may be appropriate for your application!
