An interview with Sebastian was featured recently in String Visions, the online "contemporary resource center for the 21st century classical musician" created by Ovation Press.
Philosophically there is an orientation that I think is very important. And that is, consider very carefully what role you have in the community, in any community setting. Consider what people’s perceptions are of you, and of classical musicians. Don’t assume that you will be embraced as offering a good thing. And be very conscious to think about how your interests and the interests of people living in the community you want to work in align.
