Our entire careers have been in music; we are musicians, we immerse ourselves in the work, this is our day job. Our collected experience in the music industry, over 65 years combined (25 for Eric, 40+ for Don), encompasses long relationships with many of the top artists, producers and engineers around the world.

we offer:

No hype, no B.S., no side show distractions and carnival games.

We have custom gear, a friendly dog, and nice people.

There’s beer in the fridge, good whiskey in the cabinet,,, (we don’t drink while we work — but you can!) There’s great fresh coffee in abundance. There’s also water. Fresh water, straight from the tap. We have it in bottles too. We don’t fill them, someone else fills them from their tap in another city, and we buy them. It tastes different. We’re different. Just like bottled tap water.  Only better.
