So I thought, "You know, I like some of Regina's songs, and she definitely has a different texture to some of her music, I think I'd like to see one of her live shows." So I did. It was a good show. For most of the show, the instrumentation included: drums, violin, cello, and piano. Then there was a section in there where Regina went solo and played keyboard, or completely a Capella, or even one hand playing the piano, and one hand playing the seat of a chair with a drumstick. I was impressed. I only have one of her albums, so there was plenty there I didn't recognize, but I was also pleased to hear songs I like and recognize as well. I now feel like I have seen a Regina Spektor show.The opening band, by the way, was Jupiter One and they were also quite good. Two guys on guitar, one on bass, one on drums. However, the two guys on the guitar would also play keyboards and/or violin and/or flute. And they would use those other instruments to generate loops they would layer. This now seems fairly common, but it's always fun to see a loop take shape. I had a tough time classifying the music exactly, though the style definitely sounded familiar and comfortable. I guess check some of their tracks on the website if you're curious.
