Well, MWAM is basically a japanese rock band, they been doing music since the 90's (they were used to be called Grantz), normally they make rock but mix it with pop, hard rock, dance, rap, and punk. According to their back-story, they are an artificial life form created by Jimi Hendrix to play instruments, who is described by the band as being the doctor of the guitar and master wolf biologist. It's a 5 member band consisted by Tokyo Tanaka (vocals, leader), Jean-Ken Johnny (guitar, vocals, rap), Kamikaze Boy (bass guitar, backing vocals), DJ Santa Monica (DJ, sampling) and Spear Rib (drums). They been making music for a bunch of movies (like, Godzilla v Kong and Mad Max in the japanese version of the movies), animes like Seven Deadly Sins and Mobile Suit Gundam Iron Blooded Orphans, Inuyashiki, My Hero Academia and much more. They are one of the most popular rock bands in Japan and yeah, they make really good music. You could check out songs like Seven Deadly Sins, Fly Again, Higher or my favorite one, Evergreen :D It's a really cool band but unfortunately, they are not that famous outside Japan and some other asian countries.
