pgs Guest artist series

Monthly.  All guitar styles.  All ages.  All levels.   


COVID-19 has affected all of us in both big and little ways. PGS hopes that everyone is healthy and safe during this difficult time. Unfortunately, our monthly meetings at the Tempe History Museum and all other in-person events have been postponed until further notice. We are saddened that circumstances have come to this and are eager to meet in-person again. 


However, we are pleased to announce that we will continue our guest artist series via Zoom! The PGS will host Zoom meetings at our usual gathering time of 1:30 PM on the second Sunday of every month. During these Zoom meetings we will premier video recordings submitted by our guest artist and attendees, have Q & A sessions, and provide an opportunity for live performances.


To join these monthly for Zoom meetings please RSVP to and we will send the Zoom address to you. If you would like to submit a video to be played during our open stage, RSVP to the same email address above.

If you are submitting a video please do so 48 hours prior to the Zoom meeting date. All video submissions received after the 48 hour cut-off will be premiered during the next month's meeting.
