Andrew WK is a rock vocalist, classically-trained pianist, songwriter, motivational speaker, and television personality. Andrew is most famous for his boisterous approach to rock music, characterized by shouted, chanted vocals, multi-layered guitars, huge pop hooks and keyboard flourishes (although he had since tried some experimentation, most notably an album made up of piano instrumentals). He is also famed for his persona - a relentlessly optimistic, somewhat philosophical man with an insatiable desire to motivate, or "party," as he usually refers to it. It is very likely that he is the biggest Cloud Cuckoolander in rock.Counting records only released in Asia, Andrew WK has put out six albums, although his most famous to this day is I Get Wet, which has the famous cover of his nose bleeding profusely.You can read more about all the insane/awesome stuff Andrew has done over at That Other Wiki.
Furry Fandom: According to his official website, he has shown great interest in this fandom, and as such, has received numerous pieces of fanart of his fursona "Party Animal," a winged wolf with a perpetual nosebleed.
The song also features lyrics that blatantly reference masturbation. Seriously.
Hidden Depths: That guy you heard on the radio? The one with the hard rock about partying? Yeah, he gives motivational, introspective lectures. He also released a piano-only album as a way to get away from the record company's constant demands for constant party anthems.
His music in general has got quite a lot of hidden depths. What will generally sound like simple three chord songs often hides rather complex chord progressions and elaborate melodies.
Lyrical Dissonance: "Ready To Die" is quite possibly the most joyous song ever written about murder. Granted, it's upbeat in a pretty rockin' way, but it's still not what you'd expect given the lyrics.
A lot of Andrew W.K. songs use this trope. He often sings like he's annoyed about something, but the lyrics are about fairly mundane things - partying, hot girls, enjoying yourself in various ways.
His cover of "Soldiers of Sorrow" is, essentially, a cheery upbeat-sounding rock anthem about a soldier horrified at the fact that he's surrounded by death and only survived his battle by killing people just like him.
Metal Scream: Transcribing his lyrics requires rather liberal use of exclamation marks.
Miniscule Rocking: From The Wolf we have "Make Sex," 45 seconds of primitive drumming and chants on an album filled with four-to-five-minute rock epics.
From Close Calls With Brick Walls, there's "Golden Eye Dog," 30 seconds of vocals and bass.
Three Chords and the Truth: Strangely enough, a subversion. While most of his discography consists of three minutes pop songs based on catchy hooks, most of it is actually pretty complex, in term of chord progressions and structure.
