I already said the Jackson 5 wouldn't be as great as it was without his brothers. Read my earlier posts !
Also Quincy Jones and ex CBS/Epic chairman Walter Yetnikov had more to do with help Michael being a record breakiing solo success than his brother who had nothing to do with his solo career. No one is claim Michael is an island, that's another sweeping statement.
Your wrongly accusing people of discrediting and putting Michael's brothers down. What is the exact point you are trying to make. Because you are creating a disagreement from nothing. Your the one who's not celebrating Michael's brothers, by making sweeping statements about their individual talents and success, that make Michael's brother success and talent seem less because you are over stating them.
I think Jermaine could never have had a huge solo career despite being an amazing vocalist, because it takes more then good looks and a great vocal ability to create huge success, and even more so to create a huge and loyal fan base. If Jermaine does have a fan base just for his music not connected to the Jackson 5 it will be a very small one. Most people who appreciate Jermaine's talents as an amazing vocalist (as I do) are fans of both Michael Jackson and the Jackson 5. I agree with Jermaine that the Jackson 5 is part of the legacy of Michael's incredible solo success since 1979 (though Michael made it without any family input), so from that perspective with me also view the Jackson 5/Jacksons as part of Michael Jackson I'm also a fan of Michael's brothers (with Jackie being my favorite Jackson after Michael). But that doesn't give reason to overstate the brother success and talents away from the Jackson 5/The Jacksons. I feel the success and talent Michael's brothers showed withing the group as backing singers, guitarists, base, keyboards, songwriters and dancers is exceptional, amazing. And to overstate that makes their talents seem less, because some talents function better within a group. And that happened to be a group with Michael Jackson, who was always the driving force of the group.That's not comparing Michael's brothers talents to his, it's a fact. Michael's parents said he should lead the group, and Jackie has said many times Michael had so much energy as an infant he had to lead the group, because they knew he was the person to give them success other wise they would have alternated lead singer of the group between Michael and Jermaine before they signed to Motown and when they auditioned for Motown.
Michael is a genius, and his brothers range from great to brilliant talents. I think that's a an amazing combination.
