Example Input: Beautiful Mendelssohn! . Chamber Music seems so right during the boisterous mechanics of the holidays and one sure respite from the garish noise of the external season can be found in works like the Mendelssohn Piano Trios.    Here Eugene Istomin, Leonard Rose, Isaac Stern perform Piano Trios 1 and 2 in a manner that bespeaks camaraderie of the performers as well as a complete respect for these luminous works.  Some have called these works piano sonatas with obbligato and while for this listener that is an unfair judgment, Eugene Istomin plays the piano part with enough flair and thoughtful propulsion that he does at times sound the more important.  But that is Mendelssohn's writing and not a self-aggrandizement of a pianist.    The overall sound is simply superb. These two trios are some of the loveliest ever written from that era and the gentlemen performing them offer sophisticated and informed interpretations. The recording is excellent, the music is rarefied!  Highly recommended. Grady Harp, December 05

Example Input: Ho hum . Keller Williams is a fine FINE acoustic guitar player.  I can't deny him that.  However, after seeing him live, I can't say I will ever see him again.  Too much looping, too much cheese and not enough grit.  Light and fluffy.  Maybe you could call it bubble gum music.    I'm not turned off to the jamband scene.  That's not it at all.  I was a Phish fan for many years...going back to the late eighties.  I really enjoy improvisation.  My musical life revolves around it, whether I'm playing or listening, whether its jazz, free or jamming.  I love it all.  I just find Keller Williams and a lot of the bands (not that he's a band really) that are in the "jam" scene to be pretty boring.  At least Keller doesn't go on twenty minute quasi-bluegrass noodle jams
Example Output: NEG

Example Input: Worthy sophomore effort . Out of Exile, like the debut, rocks out of the blocks riding a rolling riff that once again confirms that these guys are actually steeped in classic hard rock folklore. Again we see Rick Rubin twiddling the knobs for a fine selection of mature hard rock. Chris Cornell is again in full possession of a voice capable of putting all sorts of feeling into his lyrics. Indeed the fact that Cornell writes all the lyrics is interesting - the fact that this band has had to work out how to operate after their still talked about former bands was another hurdle these dudes had to get over. Lucky for us that they did.    This second instalment of the Audioslave story sounds much like the first which is no bad thing. The riffs are so smooth - who let the 70's back in? - and the band show full well the way to alternate rockers with mellower stuff. This album does fell a little mellower overall. Not sure if that's why the album flopped to a certain extent in certain territories but the band have corrected the slight problem of too many tracks that affected the debut.    This ablum probably shut some of the naysayers up. Sure it's sales weren't up there with the debut but it's as consistent as the first album and it's showed that this band were a serious proposition and not just a one off project and that's a good thing as hard rock needs such gimmick free bands in the mix as a foil to some of the more hysterical bands out there. In the final analysis this is a four star release for those who like their hard rock from talented players and full off rollicking riffs for the melodies to ride along.    Token non musical gripe - why the dull/crap cover
