When I first read this manga as blues rock n roll and metal lover. I always conceive myself, that the legendary musician rock music are still alive. When I saw a chapter about Jimi Hendrix played with Kurth Cobain, feels like it actually happen in real life. Jim Hendrix play "Smell Like A Teen Spirit" with his psychedelic guitar style and Kurt play "Purple Haze" with power of grunge would created a great masterpiece.
This manga makes me always that all great rock musician not only member 27 club such like John Bonham, Bon Scot, Syd Barret and every member still life somehow. Sweat spill on stage. Powerful lyric sang from their mouth. every live concert they played that I always watch. all of that always remain me that rock is not dead, and blues will help them being remember.
I hope this manga can be done. If this manga got anime adaptation, it would be a great masterpiece (however it will be hard, because of copyright).

Speaking of 27 club members, I hope the author can make character of Robert Johnson and Amy Winehouse on this manga
