Fast and professional! Thank you David everything sounds great!

David does great work! Really nice and the quality that my song has now is incredible. I would highly recommend him to anyone!!

David has been mastering my stuff for years and it always sounds incredible. Only recently have we expanded our relationship into some production work and taking advantage of his mixing skills. I have been so impressed with the end results and can't wait to continue this working relationship. He has his clients back 100%. Kiran Kairab

David has been mastering my mixes for my clients for a couple years now. He always does a great job and on time. I will continue to bring him projects for mastering because, I always receive professional work from David.
Thanks Castell.

David mixed an album for us about 20 years ago and it still sounds fresh today. We worked together again recently and he made our home recorded album sound like we recorded it in a big studio. He is a pleasure to work with and a great guy. You won't be dissapointed.

David did a fantastic job on mastering my client's EP. He worked to fit our schedule and he communicated better than any other mastering engineer I've used! Very personable guy that worked hard to make sure my client and I were completely pleased with the finished product. I'll be recommending him to every client that walks through my door!

I worked with 19 bands, several were signed by major labels. Castell consistently took a band's studio sound from flat and 2 dimensional to 3D psycho amazing. Often Castell's recordings were the first time a band sounded alive, colorful, beautiful, the way it felt at their best live performances with studio advantages. He is insanely talented!

I'm an independent artist from Dallas, TX. David has mastered several of my projects and I'm really grateful for his experienced ears, helpful mixing feedback, quick turnaround, and attention to detail. I always look forward to hearing David give a mix just what it needs.

David is an amazing talent. He is my go to for mixing and/or mastering. David is not a bag-of-tricks kinda audio pro, he really knows how to get what the song needs and what the artist wants. I rely heavily on him for his creative mind as well as his technical know how to put my songs above the rest.

I was introduced to David by a suggestion of a fellow engineer. I was working on a rap/hip hop project. In the past, I had used Bernie Grundman for mastering on at least 40 projects. I was hesitant, but tried David....to my delight. He really get has a pro interest in each different type of project I throw at him. I have used him since.

David has a fantastic ear! My experience working with him could not have been better. He listened and made the effort to understand what I was trying to achieve. Then he helped me see that there was more that could be accomplished, to go beyond my original vision. He is a true "Producer". If you need market quality, David is the man!

david is a consummate professional and the only source for 'international hit' league production in the metroplex. he took our songs and made them into nothing less than sonic magic! anyone who is lucky enough to work with him should jump at the opportunity.

I would highly suggest any artist of any genre to work with David. Not only did he send mixes and masters in a timely matter he also cared about what we as artists were trying to achieve. Overall David is extremely easy to work with and is very passionate about making your project great. We couldn't have made a better sounding album without David.

David is incredibly gifted whether mixing, mastering, vocal editing, and/or drum correcting. We've used him on two projects (in each of these aspects) and are always blown away with the results. We see David as another member of our band. Working with David is a great investment!

Dave's one of the few golden-ears, big-track-record pros available to us mere mortals. When it's time to leave amateur hour and get legit, he's the guy. He'll find the heart, soul (and balls!) of your music, and man - he's honest, hardworking, and won't rest until you're happy. First class, A+.

David is amazing. I've worked with him for 20 years and I have always been very pleased. David is a musical genius, an incredibly cool person, and an absolute pleasure to work with.
Look no further. Anyone would be lucky to work with him.

Peace.
