MEGADETH bassist David Ellefson and PocketLabWorks, Inc. today announced the new David Ellefson Rock Shop app for iPad, iPhone, and iPod touch with iRiffPort. The new app brings David Ellefson's Rock Shop YouTube series to iPad, iPhone, and iPod touch with portable guitar and bass amp software tuned with David's signature sound.

The David Ellefson Rock Shop app works with PocketLabWorks iRiffPort Digital Audio Guitar Connection, providing everything guitar and bass players need for turning their iPad, iPhone, and iPod touch into a portable practice guitar amplifier. PocketLabWorks patents pending technology with iRiffPort integrates an iTunes music player right into the David Ellefson Rock Shop app; with Speed, Pitch, and Loop controls for playing along with your iTunes music. The integrated music player makes it easy to zero in, and slow down guitar riffs for learning by ear. Real time processing adjusts the pitch automatically to standard tuning for Megadeth's hit record, Peace Sells... But Who's Buying?, from 1986, which was originally recorded slightly below standard guitar tuning.

According to David Ellefson, "The Rock Shop is an outlet for sharing my music and business experience with my fans and the music community. I am thrilled to bring this connection to the iOS mobile platform in partnership with PocketLabWorks. And, how convenient to have my own Rock Shop app in my pocket, ready for practice on the road for Megadeth's upcoming North American tour starting on January 26, 2012!"

According to Kevin Robertson, PocketLabWorks President and Lead Developer, "We are really excited to be working closely with David Ellefson on the new David Ellefson Rock Shop app. In addition to bringing David's signature sound to iOS, we are thrilled to offer David's fans an integrated experience for connecting to David's social media and David Ellefson's ROCK SHOP online."

Pricing and availability will be announced soon.

Unsung is the brand new book by David Ellefson, featuring original lyrics and images never before published, soon to be available for his fans’ enjoyment.

Dark, light, inquisitive and inspirational, Unsung expresses a uniquely diverse side to David’s creativity. He enthuses that, “as a musician, my past lyrical work has always been set to music. But, with this new book I set out to explore a new medium using both words and images as the canvas for an exciting new mosaic of storytelling.”

Unsung is also David’s first venture into the realm of self-publishing. As a result, he encourages the reader to utilize these original lyrics under license from him for their own songs. In this manner, song-writers of all levels can actually become a co-writer with David. This is truly an innovative way for fans and musicians to co-create with one of Metal music’s most iconic and inspirational artists!

As a co-founder of the rock group Megadeth, David has been a regular contributor to one of metal music’s most enduring legacies. Followers of David’s work will be delighted that Unsung proves to be yet another unique narrative from a man who is known for creating fresh and innovative ways to inspire and connect with his fans.

Unsung will be available for purchase from mid-March through Lulu.com. It will also be accessible 4-8 weeks following release from other major online retailers and local bookstores by special order. More information can be found in the coming weeks at DavidEllefson.com and Twitter.com/ellefsondavid.
