This is quite a recent song and my friend was gutted that it wasn't tabbed out so I
spent five minutes figuring out the first intro chords. It sounds accurate and my friend
reckons it is so I hope it helps :)

MY FIRST TAB ON ULTIMATE GUITAR

Artist: Dinosaur Pile Up
Song:   Barceloner
Album:  Growing Pains


   Light Overdrive
 |---------- Fig. 1 -----------|
e|-----------------------------|
B|-----------------------------|
G|-----------------------------| x4
D|-5-X-8/10-X-8/13-X-8/10-X-8\-|
A|-5-X-8/10-X-8/13-X-8/10-X-8\-|
E|-3-X-6/8--X-6/11-X-6/8--X-6\-|

I'm not 100% sure about the Mute Notes but I can hear light Mute Notes in the YouTube
video so you can choose to add/take them away if you wish.

   Heavy-ish Overdrive
e|------------------------------------| |
B|------------------------------------|.|
G|------------------------------------| | cont. sim.
D|-5-5--8/10-10--8-13-13--8/10-10--8\-| |
A|-5-5--8/10-10--8/13-13--8/10-10--8\-|.|
E|-3-3--6/8--8---6/11-11--6/8--8---6\-| |

This is played when the Drummer quits with the fast snare drum-roll and starts using the Cymbals.
I like to play it like this, but you can just play Fig. 1 without the Mute Notes.

I can't work out the rest from a YouTube vid so you can just improvise with these chords:

   G5  G    Bb5  Bb    C5  C
e|-----3--|------1---|-----0--|
B|-----0--|------3---|-----1--|
G|-----0--|------3---|-----0--|
D|-5---0--|--8---3---|-10--2--|
A|-5---2--|--8---1---|-10--3--|
E|-3---3--|--6-------|-8------|

The Major chords aren't really meant to be used but they could go well on the acoustic
guitar (I'd stick to the Power Chords (5) for this song) :)
