Well as I mentioned earlier in the thread my 1st vinyl LP was Selling England, not any sort of brag, just that I was a fan in 1979 which was about when I got it. My brother already had Three, W&W, Trick, Lamb, Foxtrot and NC so I decided to get the missing one.
I'd never thought about what my first live album was but in fact it was Seconds Out, also in 79. But I quickly fell out of love with it and haven't listen to it for over 30 years.
Ahh well the humble brag part was because the first time I saw Genesis live was on that tour and not only was it my first live album purchased but it was the first live album by a band I saw the tour it was recorded on.
Even though it wasn't from my show (MSG in February ) it felt like my own official bootleg of sorts at the time to me. I've since seen other tours by bands where they released live albums from but Seconds Out was the first and I still love and listen to it to this day. Sorry you're not into it.
