They've been playing their songs since 78 (or at least thats the date the songs were copywritten) that are in that album but the it finally came out in 83. The long wait helped it become (at that time) the fasting selling debut album by any artist in Atlantic Record's history (even faster than Led Zeppelin!!!). I rem buying it and playing it on my grandma's all in one Emerson stereo. I'm surprised the record still sounds good and that her TT didn't distroy it! Even back then at 13 years of age I was careful with my records and made tape copies and never played them again unless the tape got ruined. got their 1st 3 on vinyl, then a whole bunch that never came out on vinyl (that i know of) on CD.
they still tour. When I lived in NY, I saw them all the time. And just earlier this year , in CA (where I live now), I the saw the lead singer/guitarist sing for "the Music of Led Zeppelin" with a 50 piece orchestra!!
Check it out!! :
