I’ve just updated my list of weekly jams in Raleigh. The open mic nights at Ruckus and The Brickhouse are organised by Thomas Faucette (TJ) and Brian Jones. To get a feel for their musical tastes and abilities you can follow their Youtube channels here and here. The open mic night downtown at Zydeco is organised by Koury Thompson.
If you know of online media from people who arrange these events I would be really interested in hearing from you – get in touch!
