I saw Jimi, Noel, and Mitch live twice. I know a lot of ya’ll really love them, but I found "the middle" of the music missing in what they did. To speak in analogies, what they played created a "sphere" of music, with a hollow center. It’s like they are playing "around" where the music would normally be found, but is completely missing in theirs.
With only a single guitar (yes, played by a very creative one), a mediocre bassist (Noel was a guitarist, not a bassist) who contributed little MUSICALLY, and a drumset (played by a real fine player)---no harmony singing (and lyrics of little interest), no instrument(s) playing chords and supportive parts, and, imo, rather pedestrian chord progressions and melodies---the resulting music I find very 1-dimensional (I can hear the howls of outrage from here ;-). But what I listen for in music is particular to me, as it is for everyone.
@french_fries, as you like John Coltrane, give a listen to Ornette Coleman, another genius. Rock ’n’ Roll band NRBQ did some collaborations with another great, Sun Ra. Now THERE was a great band!
