I saw Submotion Orchestra live at Momo in London with my fiancee. The place was gorgeous- soft lighting, great acoustics, and all around very classy. The woman singing was in a beautiful black dress, off the shoulder. Her voice was soft, and sweet. Very melodic. I was not expecting the voice that came out when she started singing.
The music was a nice mix of electro, classic, and soul. Also notable was the stellar drumming and the keyboard. I noticed the trumpet especially- it really stuck out as real talent, hiding in the music but still present. The songs were upbeat but moody, and didn't always seem to mesh, but in the most wonderful way.
Basically, if you like their sound on CD, you are going to love them live- they don't need a studio to sound professional. One of my favorite of their songs was "All Yours". The crowd wasn't as energetic as you usually want at a live show, but for this, it works- everyone got totally lost in the music. We closed our eyes and just listened. I hope to start hearing their music in more places. This is the kind of music that deserves recognition, and to be on the radio.
