In response to a recent post and after a search i can find no Blues jam session info, or guidelines so i'll start it off and please add all your relevent points. views and experiences.
For me, from a house player who sees and plays lots of these, and my credentials include jam session not just in the UK but Germany, France, Holland, Italy, Los Angeles and New york, but to name a few, it is my golden rule that
"you can never be stronger than the weakest link on stage"
Its a simple rule and applies if your the houseplayer or getting up to jam. If you outplay the weakest link you will all sound bad, you will discourage him. The idea of a jam is just that... a jam not, not to show how great you are and what fantastic techniques you have. Remember jams are regular occurances so you have numerous nights ahead for others to appreciate how good you are, so don't give it all on your first couple of tries and outplay the song and those around you. Remember if the weakest link sounds bad so you all will sound bad, if the weakest link is sounding good you all sound good, and if you are that weakest link you will be encouraged rather than discouraged by this.
And remember, thank the houseplayer for the use of his equipment...common courtesy really.
