Just like fashion styles, music genres also make comebacks after a few years of trying times. It was just nine years ago when we said good bye to the era of boybands and girl groups and said hello to guitar riffs, rockstar anthems and guys with really, really shaggy hair. Now, after a lengthy and winding lull, boybands and girl groups are returning to the spotlight and ready to conquer the new phase in pop-music…

Old timers like the Spice Girls, New Kids on the Block and Backstreet Boys have reunited in the last two years to cater to dedicated fans of yesterday and now more and more new artists are coming out of the woodworks to cater to dedicated fans of today.

With fresh acts like V Factory, Wonder Girls, Varsity Fanclub and NLT, the end of this decade is in for a huge déjà vu and it’s about time!

Yesterday, we had the pleasure of spending an evening with Brooke Adams, Dominique Domingo, Noreen Juliano, Mandy Jiroux and Laura New, who — together — make the L.A.-based girl group, The Beach Girl5. These early 20somethings have everything that we’ve been longing for in a girl gorup: Youth, fun, innocence, class and most of all, music that will get stuck in your head and make your mouth turn into that shape we call a smile.

During last night’s NYC’s Fashion’s Night Out, Tommy Hilfiger hosted a soirée at his denim store in SoHo and personally invited The Beach Girl5 to perform not once, but twice, to a crowd of fashionistas, fans and curious bystanders. With their upbeat singing, synchronized dancing and endearing stage presence, the girls wowed everyone at the store… including themselves!

Fully decked-out in cute Tommy Hilfiger attire, the group performed four songs off of their debut album (which is slated to be released sometime at the end of this year) and even did a cool revival of ‘Good Vibrations,’ by their ‘father’ band, The Beach Boys.

“That was the best we’ve ever done!” Mandy tweeted to her fans. But something tells us that last night’s show will be the first of many bests for these girls, and we’re ready! Are you?
