My husband and I were visiting Portland this past weekend, and thought we'd go out for an evening of entertainment. We absolutely love A cappella groups so was delighted to find that there was such a group performing at the State Theater in Portland on Sunday evening. Since I was not familiar with this group I looked up Pentatonix on Youtube and was blown away by the talent of these five young performers. "Somebody that I used to know", "Let's get it on", "Moves like Jagger", etc. Couldn't wait to hear them do their stuff in person. Sadly, the beauty of their tight harmony, their individual talents were marred by a sound system that had no interest in their vocal beauty. The base amp was up so loud I could feel my chest vibrating! The volume on Kevin, the beatbox guy was so loud, it was clear that the only thing of interest at this concert was noise and volume. You couldn't even hear or enjoy the harmonies. It was like being at a rock concert on steroids! Additionally, the group itself chose to focus on rock style songs for a large percentage of the concert. We kept thinking that at any moment they would give us a little variety, but no...it was all the same kind of songs one right after the other, loud, fast, rockish. Jumping around on the stage, letting Kevin's beatbox dominate the group in its volume prevented the audience from hearing their true vocal talent. After a solid 1hour of thunderous base and volume discomfort, my husband and I got up and walked out of the concert. Thirty dollars down the drain for each of us. But we just couldn't stand the NOISE any longer. We came to hear singing, harmony, and talent. Their performance on the Sing Off is not what we saw in person. Again, too bad we will not be recommending their concerts to any music lovers.
