After a few months of headlining and selling out small clubs, The Bravery booked a residency at the Lower East side club Arlene's Grocery. The Bravery played every Thursday at 10pm in May 2004. Every show sold out and garnered the attention of many record labels. Around the same time, the band received their first radio airplay on the show 'Alter Ego' hosted by Paul Driscoll on Boston's WFNX. Aaron Axeleson at Live 105 in San Francisco and Zane Lowe at BBC Radio 1 in the UK, also downloaded the MP3 of "An Honest Mistake" from thebravery.com. With three major radio stations around the world playing the MP3 of "An Honest Mistake" and sold out shows in New York, The Bravery signed in August 2004 to Island Def Jam in the United States and Loog Records in the UK.  For the month of November 2004, The Bravery moved to the Stoke Newington part of London. The band imported their residency idea to London playing every Thursday at The Metro Club in Soho. The band toured the entire UK, France and the Netherlands between Thursdays. The band also opened shows for Yeah Yeah Yeahs and Razorlight.  Loog Records released the Unconditional EP, a limited edition 3 song EP on CD and 12" vinyl containing the songs "Unconditional", "No Brakes" and "Out of Line". NME wrote, "Unconditional already has the time-worn feel of an indie classic."  The cover was taken from C. Finley's oil on canvas named "Colab." "Unconditional" received heavy airplay on Radio 1 and XFM London.  The Bravery played New Year's Eve of 2005 at the Motherfucker Party in New York City. Bassist Mike Hindert was almost arrested for stripping naked and exposing his genitalia, displaying a painted smiley face and the words "Happy New Year".  The Village Voice proclaimed the Bravery to be "New York's Official Next Big Thing", while MTV and Rolling Stone hailed them as an artist to watch. The band were also tipped in the BBC News website's Sound of 2005 poll as 2005's #1 most promising act.
