No. Lego Rock Band Does not come with Instruments.
Rock instruments played in a non-rock style. Or instruments from classical and electronic music. Or not. Is a very experimental music, it can be all or nothing.
No unfortunately the instruments for rockbands are platform specific.
Yes, you can. I'm not sure of the Rock Band 1 instruments, but Rock Band 2 instruments for sure...
You can play band hero instruments with rock band 2.
Guitar Hero and Rock Band instruments were specifically designed in their own forms and by different companies. In order to prevent the usage of just one main product, each company made their instrument(s) different from the others. Therefore, no, they are no compatible. (AKA, you cannot use Guitar Hero instruments with/in replacement as Rock Band 3 ones, or any type of Rock Band.) Although, contradictory to the above, see: http://www.rockband.com/compatibility That is not true. I have Guitar Hero World Tour and I can play Rock Band 2 (not 1) and The Beatles release with my instruments. I know that I can not use Rock Band instruments for Guitar Hero.
It depends on what package you get but the main one comes with one guitar, one microphone, and one drum set
yes.sure
Yes.
No. Your nearly right. The main instruments are from the middle east and the asian continent.
Yes, the instruments require batteries.
Rock music demanded instruments diffrerent from those being produced at the time. As always, Supply met demand, and the rock instrument trade was born.
