[from Los Angeles Times (Culture Monster blog)]
The Pacific Symphony’s “Tweetcert” event is modeled, in part, on Houston Symphony’s June Tweetcert and National Symphony Orchestra performances held last summer at Wolf Trap in Vienna, VA.
[N.B. - The venues for all three organizations’ performances are amphitheatres, not enclosed, indoor (dark) concert halls, so concert-goers looking at their phone (or iPad) screens aren’t likely to be too distracting to the folks sitting near them.]
Performing arts trend likelihood: high.
