Mac OS X Tiger Training to be Unveiled at Macworld

Macworld Boston will offer some of the first public conference sessions on Mac OS X 10.4 Tiger. With classes taught by such Mac industry luminaries as David Pogue, Bob Levitus, Ted Landau and Dan Frakes, Macworld Boston will offer attendees an opportunity to learn how to put many of Tiger's key innovations to work.

"With over 200 new features in Tiger, users will be faced with a host of innovations to make their computing experience even better. We're excited that Macworld Conference & Expo Boston will be one of the first places for people to learn how to put these exciting tools to work," said Paul Kent, conference chairperson for Macworld Conference and Expo. "Whether you are upgrading one computer or your entire company, we have several conference sessions that will explain the features of Tiger and reveal useful tips to make you more productive."

The veteran Mac luminaries who will be teaching the Tiger courses are the who's who of Macintosh instruction. Instructors include:

— David Pogue is the weekly personal-technology columnist for the New York Times and an Emmy award-winning tech correspondent for CBS News. With 3 million books in print, he is also one of the world's bestselling how-to authors. Titles include: "Macworld Mac Secrets," "Macs for Dummies" and "The Great Macintosh Easter Egg Hunt."

— Ted Landau is the author of many best-selling Mac OS books and the founder of MacFixIt. With its up-to-the-minute troubleshooting news and advice, MacFixIt has become one of the most popular and respected Macintosh stops on the Internet. He is also a contributing editor for Macworld magazine.

— Dan Frakes is a respected tech writer, consultant, and Macintosh expert. He currently holds the positions of Senior Writer at Macworld, Reviews Editor for PlaylistMag, and Editor at MacFixIt.com. He is the author of Mac OS X Power Tools, an editor/author of The Macintosh Bible, 9th Edition, and a contributor to Ted Landau's Mac OS X Help Line.

A recent title includes "Mac OS X Tiger For Dummies." He also pens columns for the Houston Chronicle newspaper, MacDesign magazine, and Mac Observer Web site.

Macworld-Berklee Music Festival

Macworld Conference & Expo and Berklee College of Music will present a music festival, featuring select Berklee artists who use Macintosh computers to compose and produce music. Birdsongs of the Mesozoic, one of Boston's most prolific and original bands, will headline the first-ever Macworld-Berklee Music Festival.

The Festival will kickoff the week of July 4 at Berklee's David Friend Recital Hall, 921 Boylston Street, across the street from the Hynes Convention Center. The Festival will continue through the week of July 11 at Macworld Boston. Macworld will also showcase Berklee's Dream Studios, a simulated state-of-the-art music studio, designed and developed by Berklee faculty and students. Users will be able to take self-guided tours of the Dream Studios, participate in demonstrations and listen to presentations by Berklee faculty.

"The Dream Studios exhibit will give attendees a close-up look at the hardware and software used to build a Mac music-making studio," said David Mash, vice president for information technology at Berklee College of Music. "This will be a great chance to check out the gear in actual real-world use."

Berklee College of Music — the home of over 4,000 Mac computers — is itself a 365-day living, breathing Macworld. Since fall 2003, Berklee has required all entering students to own a Mac laptop to ensure they are equipped with the most current musical and learning tools.

Birdsongs of the Mesozoic plays a unique mix of rock, punk, classical, minimalism, and free-form music. Instrumentation is piano, two synthesizers, guitar, saxophone, and electronic and acoustic percussion. The band started in the early 80's as a side project by Roger Miller and Martin Swope, members of the Boston band Mission of Burma. They were joined by Rick Scott and Erik Lindgren for their debut recording, a self-titled EP, in 1983. With Mission of Burma dissolving at about this time, Birdsongs of the Mesozoic became a full-time band. Music Synthesis Associate Professor Michael Bierylo became the band's guitarist in 1991.
