In one of the most interesting Strip residencies and local concert collaborations, rapper Nas hired the Las Vegas Philharmonic to help him perform his classic album, Illmatic, in full. For those who don’t know, Illmatic came out a little more than 30 years ago and became an instant classic, putting east coast hip-hop back on the minds of audiences who had been completely awash in west coast hip-hop for the previous 6 or so years. Expect to hear lots of samples — soul and jazz, notably — and this is where the Philharmonic comes in, recreating the strings, keys, and horns you hear on the record.
