How I overdubbed all the alto trombone parts on Roads Less Traveled

For my CD, I recorded all the alto trombone parts, overdubbing one on top of another to create the 4 and 5 part ensemble sound. In this video I explain how I recorded the multi-trombone arrangements so that they sounded like a group being recorded instead of one guy playing all the parts one at a time. For this video, I arrange and record a new arrangement as I demonstrate the step by step process.
