(born 1964) is the former singer for EZO and Loudness
, and currently the bassist and secondary vocalist for New York City based metal band Firesign.
His career choice of moving from lead to secondary vocalist as well as becoming bassist is highly controversial to say the least, but Masaki has remained humble about the entire thing.
Tropes encompassing Yamada's 30 year career include!!
- A Date with Rosie Palms: Wild Talk, which is about phone sex.
- Anime Hair: His hairdo in EZO even rivaled Toshi of X Japan's hair in sheer craziness.
- After the End: Fire Fire, being a song about post nuclear war.
- Breakup Song: Love Kills
- Guy Liner: wears this in almost all his bands.
- Grief Song: Explode is Masaki's rage and sadness about the 9/11 attacks embodied into a musical form.
- Harsh Vocals: Even more harsh than Minoru Niihara's at times.
- Intercourse with You: She's Riding The Rhythm, Love Junkie, Wild Talk, House of 1000 Pleasures from EZO, Twisted(also Obligatory Bondage Song), Nightcreepers and Jasmine Sky for Loudness.
- Lead Bassist: A surprising lot of FIRESIGN's fans are there Just For Masaki. Masaki is best described as a Type B, as he often Vocal Tag Team s with Aya Firesign.
- Metal Scream: Did a LOT of these on stage.
- Ode to Intoxication: Wrote a LOT of these in his years in Loudness.
- Protest Song
- Racing The Wind is a Religion Rant Song, and Slaughter House is an anti Animal Testing song. He also did one of Loudness's most powerful versions of their song S.D.i. which is a protest of Atomic Hate,
- Also from Loudness, Sweet Dreams is Masaki ranting about stereotyping of Japanese people, and pretty much most of the Ghetto Machine/Dragon/Engine songs can be interpreted as some kind of protest.
- From EZO, Fire Fire is a protest against Atomic Hate, and Senso is a commentary on the Japanese government's attitude on World War II.
- Neoclassical Punk Zydeco Rockabilly: Firesign is Power Pop that occasionally plays at being Hair Metal, Nu Metal, slam, and pop punk.
- EZO's early works fell between thrash and hardcore punk, before they started singing in English.
- Rearrange the Song: Rewrote In The Mirror with different lyrics.
- Surprisingly Good English: Having learned English while living in New York with EZO, Yamada's lyrics with Loudness, although on a few albums he did have help, tended to be more coherent than Niihara's, as well as his English being less accented while speaking.
- The Deadliest Mushroom: Fire Fire is about nuclear war and the world after.
- Visual Kei: Pretty much is a Visual Kei musician still, however his style emphasizes the more metal side of Kei rather than the "pretty boy side".
- Vocal Evolution: When Yamada was in EZO, his voice was rather high-pitched and screechy, but almost punk-rock esque. By the time he exited Loudness, his voice took on a much more varied tone, ranging from reverberating medium ranged on songs such as Babylon and Jasmine Sky, to high-pitched banshee wails, like on Twisted.
