British rock band Kasabian have been called many things, from Britpop wannabes to troublemakers, thanks to their penchant over the years for mouthing off.

But they have also been hailed by many as one of the best live bands today.

The quintet's maiden Singapore gig on Wednesday night proved that they are worthy of that title.

But, if anyone was expecting to witness some of vocalist Tom Meighan's signature barbed wit - the guy has a reputation for slagging off fellow musicians, even taking potshots at U2 - he'd have been disappointed.

Meighan, as well as vocalist-guitarist and main songwriter Sergio Pizzorno, both 31, were extremely well-behaved, and were perfect gentlemen throughout their blistering 95-minute set.

The two, though not exactly chatty, frequently praised the 6,000-strong crowd and encouraged them to clap, sing and jump along to their electro-rock tunes, kicking off with Days Are Forgotten at 9.30pm.

That song was one of several on the setlist from the band's fourth and latest album, Velociraptor!, although it was older songs like L.S.F (Lost Souls Forever) and Club Foot - from their 2004 debut - that truly enthralled.

Judging by the audience's frenzied reaction to those numbers, it was clear that the headliners far outshone their opening act, lauded Brit up-and-comers The Vaccines.

The latter - a London outfit that formed in 2010 and which have been garnering major buzz in Britain - served up a 45-minute set mostly consisting of songs from their debut album, What Did You Expect From The Vaccines?, which was released last year.

Though tight musically and enthusiastic, it was clear that The Vaccines still have some way to go when it comes to perfecting a live set.

But perhaps they learnt a thing or two from Kasabian that night.

After all, the glorious rock 'n' roll swagger most prominently displayed during the three-song encore - comprising Switchblade Smiles, Vlad The Impaler and the infinitely-infectious Fire - has surely been perfected after 15 years in the business.

Talk about living up to expectations.
