One of the most respectful radioshow in Europe about Westcoast Music is Wave Music, broadcasted weekly on Sunday (8 pm-10 pm Central European Time) on RTL Radio Germany.
Hosted by Marcus Dreesen, this 2 hour radioprogram features classic hits from Westcoast Music mixed with new versions of classic songs as well as the best soft Jazz Rock in town.
A very nice place where you can listen to Robbie Dupree, Bobby Caldwell, Randy Crawford and so on.
Listen to it live on the Web for example ;-)
