I'm not familiar with Garage Masters, but I do know (or think I know) that sometimes reissue recordings can be done in good faith and not with the desire to just rip off the creative artists.
Just over a year ago I created and posted a video of my own mid-sixties group The Abstracts just for the hell of it. On several forums people responded with such comments as "That should be on Nuggets of Pebbles." I, having been out of the music scene for many years, had no idea what they were talking about so I Googled both words and leaned about the garage band scene and about the work of such people as Greg Shaw. Then, when digging deeper, I had the total surprise (shock really!) of finding that my band's long thought forgotten single's b side -- the song "Always Always" -- WAS included on a Pebbles cd. (Essential Pebbles Volume II)
I did not get paranoid about it. Instead I contacted Bomp Records, introduced myself, and inquired how that had come to be.
Instead of the generic letter from some admin assist I expected to recieve I got a very personal email from Suzie Shaw herself telling me how much she and Greg loved the song and explaining that Greg always did whatever he could to find and credit the artists. I took her words 100% with good faith. In fact no one knew who The Abstracts were. And on the record -- released by a long defunct and little known label -- even the name of the composer -- Andy Bonime -- had been misspelled.
Could I have been angry? Felt cheated? I suppose so. But in fact Greg's including the song on the Essential Pebbles cd proved to be a wonderful thing -- far more wonderful then the few dollars in royalties we lost but his using the track without being able to pay those royalties. So instead of being huffy I took the opportunity to thank all the people that had heard the song and decided to share it on their YouTube Channels and the like. My doing so was as innocent as Greg and Suzie was -- it was based on a love for the music. And those "thank you"s led to an on line discussion with a stranger about whether I had actually seen the record. When I responded "yes, it is hanging framed on my wall. I was the band's lead guitarist" a door was opened to right-hearted people to give The Abstracts the credit that they were do. And that, just one year later, led to the release of our album "Hey, Let's Go Now!" -- this time with full credit and fair reimbursement.
In truth musicians have been ripped off by unscrupulous record makers for years and years. Some even felt that way (unfairly IMO) about people like the Chess brothers. But I see -- indeed make an effort to see -- other possibilities, other motives. And in many cases I think that includes love of the music - the desire to see it "out there," being enjoyed an appreciated.
