Assorted ramblings from the world of entertainment:
In conjunction with the exhibition ''GUITAR: The Instrument That Rocked the World,'' the Carnegie Science Center in Pittsburgh will feature a program this weekend on ''The Evolution of the American Guitar.''
Dick Boak, an archivist and head of artist relations and publicity for Martin Guitar, and Craig Thatcher, leader of the blues / rock act the Craig Thatcher Band, will explain why guitars are built and shaped specific ways and discuss the history of the 180-year-old instrument manufacturer C.F. Martin & Co.
The program will be presented at 2 p.m. Saturday and 1 p.m. Sunday, and it is free with admission to the science center.
''GUITAR: The Instrument That Rocked the World,'' which runs through Sept. 30, is worth checking out regardless. The family went to the Science Center and the Andy Warhol Museum (always a favorite stop) while I was on vacation last week, and the exhibit includes some unique instruments, like guitars designed with a steampunk motif.
At the Warhol, I really enjoyed ''Donald Moffett: The Extravagant Vein,'' a survey of his work over the last 20 years. I was most fascinated by an installation called ''Hippie S--,'' which had a soundtrack of radically rearranged political anthems. Nick Lowe's ''(What's So Funny 'Bout) Peace, Love & Understanding,'' which may be my favorite song as sung by Elvis Costello, is featured in an instrumental version performed by three harmonica players that makes the New Wave-era anthem sound like a Civil War ballad.
The Moffett show runs through Sept. 9.
Bruce Springsteen sold out 11 consecutive performances at Pittsburgh Civic Arena/Mellon Arena, dating back to 1980.
That venue has been replaced by Consol Energy Center, but the streak continues. Springsteen and the E Street Band's Oct. 27 show in Pittsburgh is sold out.
Those who waited will have to deal with ticket brokers or hope for a ticket drop the week of the show.
Dreamworks' ''How to Train Your Dragon Live Spectacular'' opens today at Consol Energy Center in Pittsburgh, but performances in Cleveland on Sept. 5-8 at Quicken Loans Arena have been postponed.
According to the press release, the date change was necessary in order to allow for technical upgrades to the production. That doesn't really explain why the Pittsburgh dates are going on as planned or why the stops after Cleveland aren't affected.
The release says new performance dates will be announced soon, but it also is refunding current ticketholders, rather than asking them to wait for the new dates. Credit card purchases will be refunded automatically, and other ticket buyers can get refunds at the point of purchase.
The Rock and Roll Hall of Fame and Museum in Cleveland will have its annual Latino Heritage Festival from noon to 3 p.m. Sunday.
Entertainment on the main stage in the Rock Hall lobby will feature Grammy-nominated artist Bobby Sanabria, whose Latin musical roots include bomba, merengue, danzon, mambo, salsa and Latin jazz. Guitarist Frank Lopez will pay tribute the late Roberto Ocasio, a Cleveland-based Latin artist who died in 2004.
Caribbean, Spanish and Latin foods will be available from JiBARO.
Admission to the festival is free; however, attendees will have to buy a ticket if they want to tour the museum.
