I saw Mark Lavengood playing the lap steel guitar (sometimes called the dobro) on an amazing Lindsay Lou & The Flatbellys show at the Wildflower Pavilion in Lyons, CO, April 26th 2013. I didn't know much about the dobro until that night and Mark enlightened me.
Next night I saw Rob Ickes also playing the lap steel guitar in a different show at the same place.
After some research I found this solo album on his website for download. Mark mixes american Bluegrass with Jazz on it. It is funny and melodic.
