Recently? Well, a friend of mine who is a local reed player and has serious session cred on harp has a few bands he either plays with or created. The latest is Otto, something of an experimental quartet featuring Jim Hoke (my friend) on steel guitar (a relatively recent instrument for Jim), his son Austin on cello, and two wonderful musicians I've only met in passing on vibraphone and sax/clarinet. (Both of them are fantastic musicians.) Jim also plays a minuscule amount of harpsichord on a few tunes.
I went to see their CD release party at a local coffee shop a few weeks back and was really taken by the original and covers of some interesting stuff. They've covered two Zappa tunes and some 1940's Warner Bros. cartoon music among other great songs. The concert was wonderful.. but too short!
As for interesting stuff happening at live concerts, my experiences are rather tame by comparison. There was the time when I was out with Lila McCann that she talked the monitor engineer for Neil McCoy (the headliner) into letting her play some Cartman-talking electronic toy (as in Southpark) into their in-ear monitors while Neil attempted to sing a heartfelt love song!
Eventually he had to stop the song, explain to the audience why the band was cracking up and play the output of his IEM into the vocal mic. After feeding back into everybody
's IEM's the monitor engineer cut the monitors so the audience could hear it crackling through his mic.
Tame, but priceless!
