Saturday evening Stereophile reviewer Bob Reina's improvisational group Attention Screen - Bob Reina, piano; Don Fiorino, guitars; Chris Jones, fretless Fender bass; Mark Flynn drums - performed at the Yamaha Artist Services recital hall in mid-town Manhattan. The small hall holds 120 people and an almost sold-out crowd dug 2 sets of improvisations. Bob was playing Yamaha's revolutionary Avant Grand N3 piano, a totally electronic acoustic instrument - see http://www.stereophile.com/musicrecordings/yamahas_revolutionary_avantg…. I recorded the concert for future release as a Stereophile CD, the group's third.
