IF IT'S Thursday, it must be Balaclava.
On Wednesday, it's Timbre.
On Friday and Sunday, it's Wala Wala.
That is the bar-hopping timetable, not of a pubgoer, but a band called EIC.
And its singer Jack Ho, 30, says EIC are not the only ones doing it. He reckons that there are about 30 or so performers playing musical chairs too.
They include singers Michaela Therese and Kew Yong Fatt (better known as Fatt) as well as popular band Shirlyn And The UnXpected.
The reason so many bands are on the run, instead of holding down a long-term contract at a specific club, is that customers these days expect variety in the entertainment menu.
'Since 2005, bands have started to move from club to club more often, rather than staying at one place, because the audiences' tastes have gone up and they like to have different acts every night,' Ho says.
His four-piece band, which was formed in 2002, used to play only at Wala Wala in Holland Village.
Likewise, Shirlyn And The UnXpected were a one-club act till about five years ago, says lead singer Shirlyn Tan, 31.
Now they switch between Balaclava at Suntec and Wala Wala, she reveals.
'With different acts every night, there are so many more options and variety for audiences now,' she says.
Performers also get a payoff.
'There is variety in the crowd and we learn more about them and the different atmosphere in different clubs,' Therese observes.
'For example, those who go down to Timbre on Mondays do so to listen to music, more so than those who go during weekends.'
The 26-year-old spent the first 18 months of her seven-year singing career in Bar Celona, a pub in Robertson Walk, before she decided to ply the circuit to gain more exposure.
But the roving habit has a downside too.
Without the security of a contract, there is an ever-present risk the plug could be pulled on a band at any time. This means such bands have to be pitch-perfect all the time, to ward off unemployment.
'You can definitely make a living as a full-time musician, but the important thing is to keep your repertoire fresh and have something new to offer,' says Ho.
Tan adds: 'It would be fair if a better band comes along and takes our place; that would also serve as a wake-up call for us.'
Hosting different bands equates to higher costs but bar operators see wisdom in having such a strategy.
Ms Carol Wah, marketing manager of Imaginings Group which runs Balaclava and Wala Wala, says: 'If we have a permanent band five days a week, then the customers will be bored after a while because they have nothing new to look forward to. With different bands, there are more choices in terms of music style.'
Acid Bar in Orchard Road and Novus Courtyard in the National Museum also do not place their bets on just one band.
Their marketing director Mark Teo says: 'With the different genres of music, we can cater to the different groups that come on on different nights.
'Because the bands move around and have better exposure, they tend to have better confidence when they are on stage.'
Bar operators say it costs about 10 to 20 per cent more to hire several bands.
While Tan declines to reveal earnings, Ho says he makes about $4,000 to $5,000 monthly.
