Noone will listen to this at all i expect but seeing as my favorite band this is what i'd reccomend for Coheed.
start by listening to(in this order and keep going if you like it
Welcome Home (Good Apollo album)
The Suffering (Good Apollo album)
Blood Red Summer (In Keeping Secrets Album)
Favour House Atlantic (In Keeping Secrets Album)
Three Evils (Embodied In Love And Shadow) (In Keeping Secrets Album)
If you like that stuff, get either or both of the albums:
In Keeping Secrets Of Silent Earth: 3
Good Apollo, I'm Burning Star IV, Volume 1: From Fear Through The Eyes Of Madness
if you really really like that stuff, as those are the best two albums, go for No World For Tomorrow as the next album you buy and if you're still loving it get The Second Stage Turnbine Blade.
The four albums tell a story, which i can't be bothered to go into, but you can find out about it on wikipedia.
And if you're really really obsessed with them, Claudio has done some really good accoustic performances of various songs like: (you can find them on youtube)
Purple Haze http://www.youtube.com/watch?v=yFV2WWz6H-s
Forever Yours Faithfully http://www.youtube.com/watch?v=bCudZYXvqWk
Your Love http://www.youtube.com/watch?v=72LNnCQpTGQ
Sister Christian http://www.youtube.com/watch?v=6gC781bupVY
and loads more which are good (:
more to add, he has a side project which is called The Prize Fighter Inferno which is a one man band!
they have an album called My Brother's Blood Machine
good songs from that include:
Wayne Andrews, The Old Beekeeper
Who Watches The Watchmen
The Missing McCloud Boys
You might love the Coheed stuff but hate TPFI, but whatever just go out and listen to it if you want to.
Live performances are absolutely unimaginably amazing if you know the songs!
so yeh this probably will be completely ignored but hope it helped if anyone out there actually wants to get into the band!
