ovbox concerts

Spatially separated, but still united in a virtual concert hall through our newly developed device: the ovbox, we play consort music in times of pandemic.

Past concerts can be found on our youtube channel. Future concerts will be announced here.

Remote collaboration project: 'ovbox'

Since all our concerts are currently canceled due to Covid19 pandemia, we used the occasion to develop a remote rehearsal device. Now we meet virtually almost every day to explore new repertoire and to rehearse - with a simple small box connected to the network. See the project description on github for more details:

Harmony of the Spheres.

The movements of celestial bodies have long held a particular fascination to mankind. Astronomers and philosophers in the renaissance carefully studied the movements of celestial bodies; in their models the sun, the moon, and the five planets known at that time moved in a universal harmony, the Harmony of the Spheres. This fascination with mathematical and astronomical regularities and patterns inspired many composers, most notably during the 16th and the 20th centuries; a time when the aesthetics of numbers and proportions played a large role in the arts, from architecture to music.

Electro-acoustic concert

In our performance we project musical concepts into the spatial dimension using a 15-channel loudspeaker reproduction and low-delay realtime signal processing. The musical concepts are supported by a light installation. The sound processing has been carefully tuned to the period instruments and aims to provide the audience with a concert experience of unprecedented intensity.
