I am friends with more than my fair share of “ex rock musicians”. One group that was fairly large in the 70’s and two that were really huge for a few years in the 90’s.
For the big 70’s group, one of the guys is still making boatloads of cash today as a musician but the other two aren’t making hardly anything. One cleans a church and the other does session work and engineering.
The two bands from the 90’s, one of the main guys is still going strong as a solo artist and all the rest are struggling, living hand-to-mouth for now but getting by on some music work here and there. They’d still list their main profession as “musician”.
My business partner was in a band that could have made it big in the 90’s. they did tour nationally. But the rest of the guys were flakes and they dropped the ball for him, so he gave up and went into business for himself, not doing music.
I worked with several bands in the late 90’s of high school and college aged kids. To me, they sounded brilliant and could have had great careers. One got signed to a tiny label but I think they have all given up by now.
Another friend of mine waited until she had already had an education and a career and owned her own business…then sold the business, learned guitar and took voice lessons, wrote some fantastic songs, did a ton of work, put out an album, played a bunch of shows - and got nowhere, and gave up.
My point is not to scare little Plan B. Because all of these people I know - they may be poor, they may have lost some good friends, they may have lost out on “other” important life experiences - but I can guarantee you that none of them has any regrets about being a musician. They still love it and still play as much as they can. They revel in the experiences they had and think it was all worth the good times and bad times.
Out of these 30 or so people 2 are very rich and famous. About 10 of them are still professional musicians. The rest have day jobs and play once or twice a week, or once or twice a year. I’d say they are all brilliant musicians in their own ways. And I am glad they took a chance on rock stardom because I love their music very much.
