This is hard for me to do, but I'lll bite and try to add some spice to it.
Krautrock
Song:
Neu! - HallogalloLink: http://www.youtube.com/watch?v=ZbAWBElA6dAThis is pretty much the song I think about whenever someone brings up Krautrock. Driving, metronomic rhythm, psychedelic influences, and spare instrumentation. Granted, I could've picked CAN or Kraftwerk, but both of those overlap too much with general avant-garde and electronic music, respectively, for me to consider them as definitive krautrock. Neu! is the raw stuff of the German scene in the 70's.
Death Metal
Song: Death - Spirit Crusher
Link:
http://www.youtube.com/watch?v=woML9M5UBScI decided to go with the band that actually founded the death metal subgenre as it is known today, the Florida Death Metal band, Death. Yeah, a band whose name is actually "Death" would really need to live up to being called "Death Metal," and this song is an example of everything DM came to be known for. Screaming/growled vocals, double bass pedal blastbeats, tempos faster than thrash metal, and the obligatory shred solos. Death is everything a death metal fan could want, and show that Florida is the most evil place on Earth. Fuck Scandinavia.
Sludge Metal
Song: Melvins - Hung Bunny/Roman Bird Dog
Link:
http://www.youtube.com/watch?v=rPqnLJLOEZoYeah, "sludge metal" is a bullshit subgenre with no real guidelines, but I felt like putting this in here because it's awesome. Watch it and go download/buy LYSOL, the greatest metal album of all time (next to Painkiller).
Canterbury
Song: Kevin Ayers - Why Are We Sleeping?
Link:
http://www.youtube.com/watch?v=RKZHIT_W9F4Ah yes, I'm going to put in one of my favorite songs/performances that falls well within the actually nonexistant musical category of "Canterbury." Canterbury in itself is a catch-all term to try and desperately organize a number of bands that spawned from a fertile music scene in and around the Canterbury, UK area in the late 60's to early 70's. It all began with the Daevid Allen Trio in the late 60's, which featured future Soft Machine (the first band to truly define the Canterbury sound) members Daevid Allen, Robert Wyatt, and the hero of this video, Kevin Ayers. After the Trio disbanded in '66, Daevid Allen, Robert Wyatt and Kevin Ayers hooked up with a hipster organist named Mike Ratledge and formed the legendary Soft Machine. Soft Machine laid the groundwork for the sound that came to be called "Canterbury;" strong jazz influences, a strong sense of humor and whimsy, heavy organ/guitar distortion, and generally being ripped as shit whenever you hit the stage.
After Soft Machine, many bands came to occupy the same category, including bands such as Matching Mole, Henry Cow, Kevin Ayers And The Whole Wide World, Khan, Egg, National Health, Caravan, Gong, and many others. I'm linking this video mostly because Why Are We Sleeping became somewhat of an anthem of the whole scene, having first been written by Kevin Ayers and performed by Soft Machine during his time with them between '67 and '68. After he left, he kept playing the song live, playing it differently each time. This song also features Steve Hillage (the longhair with the crazy solo), an all-around amazing guitarist and one of my musical heroes. Steve Hillage was featured in more bands o the Canterbury scene than anyone else, including several of the above mentioned. Watch him rip it up in this video, and go check out some of the bands I outlined. You won't be disappointed.
