The ex - band member keeping Genesis alive is Steve Hackett. To be honest, his band is much better on the tracks than Genesis with Phil, Mike and Tony. I hate to say it, but IMHO is true.
That may be the case, technically. But there are quite a few Genesis tribute bands, and one of them is led by former member Steve Hackett. I saw a Genesis Revisited show by Hackett when he was in Stockholm a few years ago and it was a great experience, and I think I've managed to buy all live CDs he as issued during recent years. However, I definitely prefer the contemporary Genesis playing songs from their own past. In plain text Genesis in 2021 has three musicians who have been with the group for more than 50 years plus Daryl (40+ years). This means that when Genesis perform their songs there is the personal and emotional bond to these songs, that can't be achieved by putting together a tribute band. There's certainly nothing wrong when a solo artist performs songs from his former band, but it will always be a solo concert with things being a lot different than the mother band.
