Oh man just had a talk about this a buddy of mine yesterday...
John Frusciante: Definitely. He's argued one of the best guitar players of our generation, most notable band he played for was the Red Hot Chili Peppers. He's an inspirational dude because as most 90s rock stars, he was a drug addict. Shot up heroin, acid, cocaine, you name it. It got to the point where he just stopped playing for the band and secluded himself in a little apartment. According to him, he fell under the pressure of being famous(they literally got famous overnight with their album Blood Sugar, Sex, & Magik) and fell into all those bad habits. Johny Depp actually did a short documentary on him while he was all drugged out; he takes a camera around his apartment and you see how shitty he lives and how low he actually got; its really disturbing.
However what makes him so inspirational is he lived through what so many other artists died in. He was able to pull himself out his shithole life, stay clean, return to the Chili Peppers, make another great album, and then leave the band to pursue different musical interests. Great guy, great guitar player, and definitely inspirational in my book. I'll post a few links from youtube and you guys can check them out if you wish.
Other people include Jimi Hendrix(he is considered the "Guitar God" after only being 4 years in the business; to accomplish what he did in 4 years is just amazing), Gang Starr aka the Guru(underground rapper from the East Coast that passed away last year due to cardiac arrest at age 43, one of the first rappers I ever listened to and definitely had a positive message in almost all his songs), Buddy Guy(in my opinion the best guitar player currently in the world; his life story is just too long to write in a sentence, but he is definitely an inspirational dude if you decide to look him up; him and B.B. King are truly living legends).
Yeah all my inspirational people are from the music industry. What can I say? Music has a special place in my heart :).
