Los Angeles: YogiChocolate
I stumbled upon YogiChocolate because who wouldn't be tempted by the words yoga and chocolate? I also thought it was an ingenious idea and a great resource. Basically, the Santa Monica based company offers a slew of mp3 audio-classes for download on a donation basis, which means you pay what you want.
The selection of teachers is international (Russia and Asia are in the house as are folks from all over the country like Gary Halperin, Desiree Bartlett, Gurutej, Aras Baskauskas and Bryan Kest). The type of practice available is varied (Power, Jivamukti, Kripalu to name a few), and there are even audio files with mediation and kirtan.
For me, YogiChocolate is a great way to augment my home practice and to make any vacation a retreat. Beach yoga, anyone?
