Stuff recorded solo can be OK, but from what I've heard, only if the recording quality is very high. Dominic Taylor in Limerick is on the ball with the way he records his open mic - White House Pub every Wednesday - and certainly the highest recording quality of live poetry I've heard.
I put a few of my own efforts out last year after becoming gripped with a desire to claim the sad statistic of being the first in Ireland to podcast poetry online and learned a lot from the whole process. I imagine that hearing the voice this way is the closest one can get to being in the audience and a useful tool in the kit bag.
I found that - the more I recorded - I became less interested in putting my own voice out there, rather work with other voices and this evolved into making found poems this way, cutting and splicing various lines from different voices and putting them together.
Tony Lamb in Cornwall produced a very good CD of poets living in that county, with specially commisioned music behind each one.
Also, Larry Winfield in California has an excellent online poetry show and the weekly poetry show on RTE Radio One hosted by the excellent Pat Boran- The Enchanted Way - broadcasts online.
You have to download Larry's show, which can take a fair amount of time, but The Enchanted Way is streamed and you will need realplayer to hear it, but there is now download waiting time.
