John McLaughlin's soul and music are not easy to approach. He is not BBKing, John Williams, Segovia or Clapton. He is also technically at a totally different level than others, though at times Paco de Lucia was absolutely great too. Passion Grace&Fire is a better album by the trio, digital studio recording.
Friday Night concert was just one performance of a world tour and it was not the best. Nor was the selection for the album. The best concert of that tour I heard on youtube was in, I think, Freiburg Germany. The performance of the composition 'Spain' written by Chick Corea is a masterpiece even by their standards, especially John's guitar.
After that concert in Germany you could try Yngwie Malmsteen with New Japan Philarmonic playing neo-classical compositions. Very impressive, orchestra too.
