So, this is a list of bandom recs for morganmuffle. It was going to be posted as a comment elsewhere but as you will see it got away from me slightly so I thought I might just as well post it here. So Sarah, I may have recced these before, you may have read them of your own accord, but here they are in a list. Separated by band. Rubbish descriptions, if at all. Sorry. It's all a really random selection - not necessarily the big name fics in the fandom, but ridiculous stuff that I like. Still, it'll keep you out of mischief!

Panic

Drink Me Verse. Ryan/Brendon, steampunkish. Brendon is a potions apprentice.
Drink Me The worst thing was that Ryan, the boy with the newsboy cap and the shy smile, didn't know about the love potion.
I've got a question for my dragonfly (Wee Jon/Spencer interlude)
Little Blue Fish Ryan finds out about the love potion
The Lamp Eater Whatever the creature in the streetlamp is, Brendon's never seen one before.

Five Notes to Fall Apart to Spencer/Brendon. The angsty one I was talking about. I can't remember if I recced it before or not.
Call it home Spencer/Brendon. Space sex slave fic!
A throat-pierced sound in the night Jon/Ryan. Jon is the sort of guy who stops to pick up hitchhikers.
God only knows Otherwise known as boywives!!!!!! A Big Love AU (basically the rest of Panic are Jon Walker's boywives. It is marvellous.)
Nothing Quite Like Jon/Brendon. Crossdressing, underwear fetish and sniff kink.
Pull Your Tangles Out Spencer/Brendon, D/s. Brendon does what Spencer tells him, but it takes Jon remarking on it for Spencer to really notice.
If I ever lost my Jon/Ryan. One of the funniest fics you will ever read. Jon wakes up and his legs have fallen off.
Only Unto Him Spencer/Brendon. Harlequin AU with a virgin bride \o/ As a Prince(ish person), Spencer was meant to be pure in every way. He didn't know what to expect from an arranged marriage — but certainly not Brendon's incessant grabby hands. Who did this bouncy, mysterious stranger think he was? AND ARE SEXY TIMEZ EVER GOING TO HAPPEN? [Hint: it is quite likely they are.]
The Birthday Special Spencer/Brendon. Kind of angsty. Spencer has a bit of an early midlife crisis.
But not the song Epic slave fic.
Dear catastrophe waiter Brendon/Ryan Ryan the prettiest waiter in all of San Francisco
Walk the line BB!Ryan/Spencer ♥
Till you make it Jon/Brendon. The high school AU of my heart - fake boyfriends, makeovers and prom!
Like explosions in the sky Brendon/Ryan, Jon/Spencer. Dystopian AU. Angsty.
Blindsided by your smile Jon/Brendon. High school AU, Jon finds Brendon in the bathroom after his glasses have been stolen.
But where do the nuns come in? Brendon and Ryan go camping with Brendon's family.
Wednesday Night Boys The Whore AU. It's ridiculous and the characterisation is terrible, but it's glorious at the same time. MCR feature.
if music be the food of love Spencer/Brendon, babyband. This is the one Chloe and I read at Connotations.
Ryan Ross: Wedding Planner Jon/Spencer, Ryan/Brendon.
Pretty much a sex god Jon/Spencer prequel to the Wedding Planner fic.
(Panic! at the Disco Almost Changed Their Name to) Fuzzy Kitten Cuddle Time Panic turn into kittens. Adorable.
As close as it gets to home Telepath AU!
Maybe a bird with a people face or a bear with pants on Spencer/Brendon Brendon the milkman befriends Spencer the lonely drunk housewife.
Everybody's living like they're crazy in love Brendon/Cash (from The Cab). Boyfriends and they didn't realise it.

My Chem

The Rise and Fall of the Black Parade This is wonderful, but is based heavily on the album The Black Parade so it might not be as great for you.
Mixed Bathing at Home Frank/Gerard. Gerard gets his toe stuck in the bath tap, Frank has to rescue him.
The Old Straight Track Frank/Gerard. Frank is a ghost in Gerard's apartment.
From the corner to the block Frank/Mikey. Bike messenger au.
Our Love is Like a White Steed Equipped With An Ivory Penis Symbol Atop Its Head Frank/Mikey high school au. Unicorns! (Mikeyway has a canon love of unicorns)
A cage went in search of a bird Bob/Frank. Slave fic. Awesome.
Skin of the canvas Frank/Gerard. I've always wondered why, when Gerard decided he wanted to save lives, he turned away from visual arts and started a band. This is an AU version of one answer. Gerard is still at SVA, having taken a while away to enter AA and get sober; Frank is a nude model and punk rocker who's moved to New York City. Romance (and sneezing!) ensues.
A Lovely Apparition (or, The One Where Gerard's A Crossdresser in the 1790s) Frank/Gerard. Title is fairly self explanatory.
And I dream of what I need Frank/Gerard. Gerard is a Princess. Oh yes.
Crazy mad for him Frank/Gerard. They see each other on the train every day.
Nightswimming Frank/Gerard. High school. This gets recced to n00bs all the time. It's VERY long.
Home is a Name Goes with the Panic Whore AU. Just as ridiculous and lolzy.
Forever, Now Giant AU in which Brian (MCR's manager in RL) adopts the homeless Way brothers. There are many continuing stories to it.
Something Better Frank/Gerard. Frank takes a job as Gerard's nanny. As in, the nanny to Gerard's daughter. This isn't a paedo au.
An inexplicable occurrence of angels Frank/Gerard. Frank is an angel.
On measuring life with coffee spoons Frank/Gerard. Frank is a barista, Gee is an artist and also slightly stalkery.
Buy Handmade Frank/Gerard. Etsy au.

FOB

thnks fr th mmrs Pete/Patrick, high school au. Patrick hates yearbooks.
The true story of what never happened Pete writes FOB badfic, Patrick is his beta.
The last good thing about this part of town Pete/Patrick. High school. Pete is Patrick's teacher
Many things lacking names Pete loses his shadow. This is very weird, but very good.
This story's going somewhere Pete/Patrick ageswap, ie Pete is 16 and Patrick is 21.
Make my troubles rhyme Pete/Patrick. Pete goes through the looking glass
Gather no moss Companion piece to Make my troubles rhyme
Patricksitting (call it a love song) Pete/Patrick. Patrick's mum leaves Pete in charge of Patrick when she goes away. Bad idea, Mrs Stumph.

Multi Band

The Risen Zombie AU on a cruise ship.
Of Angels and Kings We are a generation of displaced souls. We have lost what it means to be human. What is justice? What is love? We have been ravaged by war, plunged into darkness, exposed to our own failings. We were forced to grow up in the middle of war, our adolescence and early adulthood stolen by war. This generation will be a lost generation, seeking to find itself in the rubble of humanity. Excerpt from Angels and Kings: An Essay by Pete Wentz, published May 1919.
