There's no question that Christmas brings an opportunity for music groups to make some money. Just like the "Nutcracker" in the ballet world, Handel's "Messiah" is almost a sure bet to fill all of the seats in the house. There is usually plenty of people who either want to sing this piece or hear it. The Portland Baroque Orchestra has done very well with their "Messiah" concerts over a number of years and have added a "Messiah" singalong concert. For those of you who missed that singalong, you have another chance at Central Lutheran (1820 Northeast 21st Avenue) on December 18th. (The Central Lutheran singalong is not a PBO event.)
But aside from the Messiah concerts, there are many other holiday concerts. One of the best places to find out about them is to look at the PDX Choral Calendar. This calendar contains dates, times, and links in a simple format. Please take a look at this calendar, and you'll find a concert that will help you to get into the holiday spirit.
