I've known this young lad since he was born. He's the son of Landecker and the Legends guitarist Mark Gardner, and he was born around the same time as my oldest son Tommy.
We used to go to Mark's house every year for a Legends Christmas party, and little Dylan would be playing the drums in their basement (I seem to remember him doing this at a ridiculous age like 3 or 4). Dylan has also appeared on stage with Landecker & the Legends, most recently in 2009 when he performed the Doors song "Roadhouse Blues" at the age of 13.
The Gardners moved out to Arizona shortly after that show, but it's obvious that Dylan's musical career is just getting started. He plays guitar, bass, and piano on the song. I'm very impressed with the youngster.
