Is 24 too old to become a hip hop instrumentalist, especially if I have no experience & am willing to learn?

its never too late. if your into hip hop making beats can be a really fun albeit very expensive and difficult hobby. theres alot of equipment that you have to buy and master. try to go to your local guitar center. you could actually play all the equipment there in the pro audio section. its gonna cost you about a thousand to get up and running on your own.you need a drum machine, keyboard, and a sampler like an mpc is important. good luck.
