"ALEXANDRA PALACE!" woofs frontman Justin Young - flaunting the indie Brian Blessed look - after a high-strung opening of 'No Hope' and 'Wreckin' Bar'. Those inside, almost half of whom seem to be donning Vaccines tees, are probably somewhere between too soft for Kasabian and too hard for Two Door.
There's a real familiarity about the first album's hits; 'Wreckin' Bar' and 'Post Break-Up Sex' do a job of feeling 'classic' even though they're only a couple years known. The guitars are thundering and the hooks so tight, it's hard not to get down on it and lap up their anthemia.
The change in sound on both their albums isn't really felt in here, either. Though Come of Age is more crisp and less fitful than its predecessor, the whole set pretty much moulds into a fat blast of spunk and guts; 'Aftershave Ocean's lovelorn tale is especially stirring when amp'd up so roaring.
And are the band nervous playing their biggest headline show yet? They certainly don't look it. Guitarist Freddie Cowan spends most of tonight smiling at the size of the crowd, while Young rhapsodises at one point: "This is the best f**king night of my life. I love you!" Awww…
'Wetsuit' is a moment, too; the only thing that could make its slushy keys-led build-up even slushier is if When Harry Met Sally was playing on the stage's backdrop. We get one final snivel from Young ("I remember when we played to 10 people, let alone 10,000") before an unhinged take on 'Norgaard' suitably sees 'em off.
This band have had their Strokes accusers in the past and they're first to admit they're not the most inventive, but in times of Rihanna-rotated over-produced blather, The Vaccines are a shining light for good and tonight was anthem after anthem. Now go play the f**k out of that arena, lads...
