Well, it's finally happened... Age discrimination.
After playing a particular local venue several times over the past few years with great turnout, a packed house of diners, drinkers, and dancers, then getting no replies & no return communication to our attempts to book more dates, we learned this:
A friend who plays in another band that has played this venue regularly and has also been getting the cold shoulder was told by his booking agent that the venue's manager said he doesn't want any more 'grey haired old guy bands' on his stage. He wants 'young bands who can draw a younger, cooler clientele and not players who look like their fathers'.
So I guess it's all about what you look like at this place.
This venue is dead to me now.
