Live Nation's roll-out of "No-Fee Wednesdays" went pretty well - the company reported a 500 percent spike in business last week. Even though not everyone is biting - "The problem is concertgoing is no longer a regular ritual for most of the public, it's something they do at most once a year, which they overpay for," said online music-biz watchdog Bob Lefsetz - the concert-promoting giant is once again offering tickets sans service fee all day Wednesday at www.livenation.com. Only for shows at Live Nation-owned amphitheaters such as the Cynthia Woods Mitchell Pavilion, though. The Summer session of Nameless Sound's Creative Music Classes for Young People" begins June 16. All classes, offered for youth from kindergarten through eighth grade, are free of charge. See www.namelesssound.org for more. Keep up with volume-abled Houston post-rockers Golden Cities' very first tour ever on the band's "Space Rock from Space City" blog. They've already seen "a car literally turning across three lanes of traffic & crash into a barricade, with the driver walking away from a completely totaled car" in Atlanta. Stay safe, guys.
