Mav, Missy Higgins is getting a lot of air play on the University of Pennsylvania college radio station, WXPN (www.xpn.org)I think?). It is absolutely the bast Americana and Adult Alternative station here. The syndicated "World Cafe" show is taped here as well. The COWBOY JUNKIES are Canadian and are fans of TOWNES VAN ZANDTwho in return has a song called COWBOY JUNKIE'S LAMENT.
Townes was a legendary singer songwriter from Texas who is considered one of the major influences of Americana. I have a live show of Townes, Steve Earle, and Guy Clark. It's great, if you want a copy, I'll burn it for ya
