I make this post in the utmost respect to many of the bands here. It takes a lot of love for a band to admit their mistakes when you really like them.
John Mclaughlin: When he created the John McLaughlin trio in 1988, his first choice of bassist was Jeff Berlin. They didn't get on, apparently and their was allegedly some conflict because Jeff wanted to have his amp on stage during the live shows, which John didn't want. Whatever the reasons, Jeff left the band and was replaced by Kai Eckhardt, who was a good fit. However, I've listened to the bootlegs of the original trio and it is John McLaughlin at his most senstive and soulful, accompanied by the best gun for hire bassist in the business. I could weep for thoughts of that trio not working out. They are good friends now but I feel the opportunity was missed to forge a great recording history between two world class talents. Jeff could have taken McLaughlin's music to a higher plane.
