Here we have another Prog Rock trio, this one much different than yesterday's (Rush). ELP, along with early Genesis and Yes, are my three favorite Prog Rock bands. Keith Emerson has been mentioned as one of the best, if not the most technically accomplished keyboard player in rock history. This live album, of course with no overdubs or retakes, is a great example of the talent, creativity, and imagination of Emerson, Lake, and Palmer. The trio plays a tight adaptation of a classical piece by Mussorgski. The pipe organ, multiple synths, acoustic guitar, bass, and drums all contribute to this impressive work.
