Two of the clubs we play will only book shows via Facebook message. Just now, paid my band using PayPal for the first time. We share a Google calendar that we all use for blackout dates, shows, rehearsals, etc. My guitarist and I share charts. He just sent me one. I printed from my phone using my wireless network printer. My whole lighting rig weighs 30 pounds including stands. I control it wirelessly via a foot controller on stage. It's bright enough to melt your retina and has 7 colors per light. It takes approximately a minute and a half to set up. My church uses Planning Center online to do all of the above (except pay....which we don't want). I learn my songs by syncing my Spotify account with the AmazingSlowDowner app, and Bluetooth those songs to my little mixer where I run my bass, songs and vocals into headphones, which are IEM buds with 5 tiny speakers in them. That same guitar player uses whatever the newest and greatest Line6 modeler is. As much as I hate to admit it, the thing sounds incredible. Lots of bass players have amazing sounding, stupid loud rigs that weigh fifty pounds total.... or less..... some way less. Our PA....including subs.....would fit into an average minivan....with room for drums. And its ridiculously clean and loud. We run sound from an iPad. I'm able to tweak my in-ears mix from my phone. We save an image for every place we play so that all we have to do next time is turn the dang thing on and start playing. I'm posting this thread for the whole interwebz to see using my thumbs.... and a phone. When I started this little journey into live music, band organization took place over the phone lines or in person. I actually got a few checks in the mail the Tuesday after gigs. Charts were hand written. Songs were learned from cassettes you had to buy to get a song or (hopefully) somebody in the band had.... and would make you a copy from a double deck. Transposing was on you. Every rig weighed a metric ton. PA weighed even more. It's a fascinating time to be in music.
