I heard their first single "The Adventure" back in 2006 and liked it a lot, esp as a previous fan of Blink 182 back in my High School days.
Then I saw Angel & Airwaves live when they supported the Foo Fighters in June 2006 in Manchester. I enjoyed their performance, and some good songs, although Tom DeLonge did start talking some crap about post 9/11, Iraq bollocks, which the crowd really didn't care about
I bought their first album We Don't Need To Whisper the next day, and yeah its great. Some awesome tracks on there, it's got a very Boxcar Racer feel to it.
My favourites tracks would be The Adventure, A Little's Enough, The War, and Good Day
I got their second album I-Empire in November 2007... hmm. Not impressed.
To be fair I only listened to it about twice, and haven't really given it another try since. I'd just rather listen to the first one
btw, have you heard Mark Hoppus' band +44? It's ok, more in the style of B182 than A&A
