i saw 2 friends do a 1 1/2 hour show. i enjoyed it and respect them both as songwriters and musicians. Each of them had a phone mounted on the mic stand. it amazed me how dependent we have become on this technology. i find it distracting when someone has to scroll in the middle of a song. They each did songs separately and a few together including some originals.. I wonder why it would be so difficult to learn enough material for such a short set shared by 2 people..?? i have seen super talented people use their phone when performing their own material also.. being mesmerized by their performance, until they look down and scroll the phone. Breaks the spell... i also have seen when they have to start a song over because they got lost when scrolling... maybe I'm old school, but i just dont get it. Now i also have a friend who takes requests for over 500-600 songs. you text your request via his app from the audience, he gets your request on stage while he is playing, and plays your request next. I would not expect him to not need a tablet for song keys and lyrics.. i have seen him play for 3 hours straight. he has midi, pedals and is pretty much a one man band. he is awesome. what are your thoughts ???
