wet T-shirted” violinists

Crossover! Heaven forbid! To many classical music critics and tradition-minded artists, the commercial crossover projects in the last two decades are sure signs, in the words of the esteemed British baritone Thomas Allen, that “well-organized hijackers” and “money-grabbing, P.R.-led” marketers are using “wet T-shirted” violinists to — horror or horrors — sell classical records.

A popular vulgar entertaiment is a "wet T-shirt competition" in which young women wear T-shirts without bras under them. The shirts are then wet, which renders the clothing rather clingy, thus making it stick to the woman's torso. This enhances the view of the frontal aspect of the lady's anatomy.

What Allen is objecting to is the concept of getting people to like classical music by having such woman violinists appear in wet T-shirts.

"Money-grabbing" means "getting lots of money to come in very quickly".
"PR-led" means that the main focus is Public Relations - they are using the advertising to sell the record instead of allowing the music to do it.

PS - Raymott, that is the politest explanation of a wet T-shirt competition I've heard in my life!

Well that's just from what I've been told. I don't have a first-hand knowledge.
