It may not be the most wonderful time of the year (that's Christmas-New Year, fyi) but with the weather being as it is, it's a pretty nice time to be in the Philippines.
What's great about this season is that there are a lot of shows going on. For those who like musicals, there's Wicked showing at CCP. There are also some pre-valentines shows to look forward to.
For me, I love the fact that a lot of concerts are held from January to March - for free! It's graduation season and end-of-the-year recitals are common. Admission is usually free (solo recitals), and you get to support some budding young talent. After all, occupied halls are better halls ^^
Check out the universities near you, especially ones you are alumni of. Chances are there are posters in the local music department.
It's a great way to start the new year :)
