Stills' voice was never his strong point, but he could/can sure make an acoustic guitar SING!
Interestingly enough, Stills played a lot more electric than acoustic guitar last night. As far as his vocals are concerned... they aren't slipping, they're (sorry to say) practically gone! If Crosby had 95% of his vocals and Nash had 90% of his, I don't think Stills had 30% of his. Too bad, because other than that it was great show!
The cover tunes were fun, although it's kind of strange to hear CS&N cover the Stones or the Who. BTW - Stills imitation of the Townsend "windmill" on guitar was even sadder than his vocals! Very weak.
For me, I think the Beatles, Allman Bros. & Dylan covers came across as more believable style-wise. I guess those songs just fit CS&N's acoustic guitar vibe better?
Nash & Crosby's vocals, especially when harmonizing together were great. I thought Guinnevere as a duet was incredible. (It happens to also be a personal favorite of mine.) Then again, I love all of their stuff. To me, their whole catalog is almost like a greatest hits. I would definitely go see them again. Too much great music to pass up hearing again!
