"The Continuum blew my mind in that it is sort of a fabulous hi-speed collision between a piano and a Theremin and yet something totally unique and totally expressive. Also the sounds that have been painstakingly designed specifically for the instrument are gorgeous!" says Schwimmer.
See Schwimmer perform a version of "Because" by The Beatles.
It has a funny name and it looks ancient but in fact there has never been an electronic instrument quite like it.
"Eight analogue oscillators hum slightly out of tune with each other, which is the reason for the name: the discordant chaos sounds like being in the middle of a swarm of bees," explains Roger Cordell from Big City Music, who are the main distributors of the Swarmatron.
"The artist can control the color, intensity and direction of the swarm with an array of controls, but never to perfection, so working with the Swarmatron is always an adventure."
Fans include Trent Reznor, who used it for the soundtrack to The Social Network and British producer Dan Carey, who has worked with big name artists including Franz Ferdinand, Hot Chip and most recently, Emiliana Torrini.
"It's such a sensitive piece of equipment that when you manipulate the controls there are almost an infinite number of harmonies. I've never heard anything like it before. The noises it makes are completely unique and otherworldly," says Carey.
Carey's label Speedy Wunderground, on which he records tracks in just one day, has 10 commandments. Rule number seven is: "Somewhere on each record the Swarmatron will make an appearance."
