Mad props to Philippe Graffin for sending us a link to this clip showing the utterly incredible violinist Toscha Seidel playing a few tantalizing seconds of a Brahms Hungarian Dance.
Seidel, whose tone could burn down a house, was a one-time rival of Heifetz in the class of the great (Hungarian) teacher Leopold Auer, but I remember hearing once that Heifetz was considered the tough cookie who could survive a heavy-duty international career and was therefore selected for pushing. The results go without saying. Seidel never emerged from his shadow and ended up in Hollywood, where he performed on the soundtrack to Intermezzo (Ingrid Bergman's debut) and recorded Korngold's Much Ado About Nothing suite with the composer. A discussion about Seidel on www.violinist.com, which I've just found, also suggests that he played in a band in Vegas. Oy.
If anyone has access to any more film of Seidel, we slidey violin fans would be forever indebted if you were to post it to Youtube, pleasepleaseplease.
