This was the first jazz album I ever purchased, in 1970. After hearing it being played next door from my college neighbors room, I ran over to ask him who that was. It was to be the first of many such trips next door, as my neighbor had a superb collection of jazz that he educated me on. I then went to see Gene Harris and the 3 Sounds that very same year, at Watt's Club Mozambique in Detroit, but his line-up had changed from the Symphony album. It was his Killer Joe tour and I wasn't disappointed. He even stopped by our table to greet us, as he made the rounds around the club. I think I've played this album more than any of my other albums, including my Miles Davis or John Coltrane albums. Symphony?, Jazz? , what's going on here? The level of sophistication is extraordinary, and cannot be recommended highly enough. Gene Harris was always the strongest keyboard player, but his sensitivity on the softer passages on this album is incredible. I love this album!!!
