Upon deciding to make the switch to upright bass, I'm now seeking decent quality audio/video recordings of bassists in small ensembles, who demonstrate impeccable right-hand technique without amplification. In other words, representative samples of a variety of different sorts of ensembles in which purely acoustic instruments work together effectively. The key is no electric amplification. There are hundreds of YouTube videos of bassists who are relying on their amps to keep up with the other instruments, and therefore haven't striven to develop the particular skill I am looking for. I'm picturing a group that is probably smallish, with anywhere from about three to seven players and/or singers, so that the unplugged upright bass is prominent, and not lost in the mix. Genre is of no concern.
