Walang kaabug-abog na binirit ni Katrina Velarde sa isang concert ang bagong areglo ng OPM classic na “Anak,” isang araw lang na preparasyon bago ang mismong performance kung saan si Popstar Royalty Sarah Geronimo sana ang kakanta.

Matapos magkasakit ni Sarah G sa unang araw ng anniversary concert ni Maestro Louie Ocampo nitong Sabado, Pebrero 4, to the rescue ang Pinay biritera na si Kat para ituloy ang show.

Bagaman “challenging” ani Kat, maning-mani ng Pinay diva ang pangmalakasang areglo na parehong may genre na rock at power birit.

Sam Verzosa, nakikita na bang 'The One' ang partner na si Rhian Ramos?

“It was verychallenging learning the song day before the show. But I’m very thankful and honored to be a part of Louie Ocampo Composer Ka Lang Concert,” ani Kat.

Sa dulo ng performance, makikitang maging ang batikang maestro ay hindi makapaniwalang isang araw lang inaral ng singer ang komplikadong areglo.

Instant viral ang performance ni Kat na umaani ngayon ng positibong komento mula sa kaniyang fans.

“WA ko ma-say! Sobrang pinahirap ang pyesa pero na-perform mo perfectly salute to you MsKatrina Velardekudos also to Sir Louie Ocampo sa very fantastic accompaniment-a certified great musician!” komento ng isang fan ni Kat.

“The fact that they chose her was not a regretful decision. She made a statement by performing it more like an emotional song that turns to a rock song. ANG GALING MAMSHIEEE!!!” dagdag ng isa pang netizen.

“Wowwww. Grabe halimaw!👏👏👏👏👏

“Kudos! And to think that you only had few hours to practice for this beautiful areglo by Mr. Louie! You did great. SLAYED!”

“Wow Katrina can belt as high as heaven and she is really super good, and Sarah Geronimo when I watched her version she can really be anyone' and put a show. Two great artist singers!”

“Sarah G must be so proud!👏🏻

“Napakahusay mo KV! Yung reaction talaga ni sir LO, kinikilabutan ako. Ganda Ng arrangement. Meant for you.❤️. So proud of youuu. Congratulations!🥰

“Got some chills all over my body, one of the best singers of the Philippines, looking forward for her own segment TV show.🙏💓😘Go go idolKatrina Velarde😘, more shows to come.”

“Napakahusay mo talaga Katrina! Nilamon mo lang nang walang effort!”

“All I know this arrangement was made for SG and I have seen her videos gazillon times and its superb and now here is KV my ghadddd you have given so much justice to this arrangement mamshhh. I can't stop loving you talaga!”

Sa ngayon, nasa mahigit 227,000 views na ang viral video sa Facebook pa lang.

Samantala, sa isang Instagram post, nagpaabot din ng kaniyang paumanhin si Sarah G kay Ocampo, at sa fans matapos ngang hindi makapagperform nang magkasakit.

“Babawi po ako sa inyo next time, Sir Louie at sa lahat ng Popsters," aniya.

Binati rin ng Popstar ang tagumpay ng unang show nito.

"Congratulations Sir Louie Ocampo on the success of your show last night!! Thank you for being the coolest Musical director that you are. I am so blessed to have been given many opportunities to work with the one and only Maestro Louie Ocampo!!"
