I'll echo the sentiments towards
? being a good place to start. I'll also add in
One, but do yourself a favor and PLEASE get the Special Edition with the bonus disc! The extra tracks (non-covers) actually work into the album's story-line/concept and "King Jesus" is just a killer tune!
I'll also go out on a limb here and say go out and buy
Testimony Live. You get the entire
Testimony album in a live setting with Neal, Mike (yes! He plays drums live on it!), and 7 other great musicians playing (including Randy George, who wasn't on the studio release of
Testimony). After the daunting 120+ minute
Testimony, Neal and company come back on stage to play an amazing encore of "We All Need Some Light", "The Light" and "Stranger In Your Soul". It's one of my favorite live DVDs (next to Transatlantic's Live In Europe), and I would recommend it if you want to experience Neal in a recorded, live setting performing his solo stuff.
If you want a live album, I wouldn't mind suggesting
? Live, which covers the entire
? album, some tunes from the Special Edition of
One.
Pretty much any of his live releases cover the majority of his albums (with
One and some of
Sola Scriptura, as well as a couple songs from
Lifeline, having not been released on any live CD or DVD). Once you get a couple, you may get hooked and get them all, like I have... but, to be honest, that's quite alright!
