Yes. Check at your hotel or websites about San Antonio entertainment.
Howling at the Moon, has the Dueling Pianos. Check out their website: howlatthemoon, San Antonio. just spent an evening there Thursday Sept 21st. Had a great time with friends.
Yes there were a couple of sports bar/ restaurant places with live music. Don't remember their names but seems they were centered or close to the main boat launch. Above the river walk there were also a couple.
Music all over the place, even had a Mexican band on a bridge as our boat passed under it.
Lots you just have to pick and choose close to your hotel, the river walk has restaurants on both sides, a lot of them have bars and music
If you are only there for a few days suggest you pick a hotel close by to the river walk and search for music and bars on the river walk
Haven't found any, but there is a couple of touring players, who will sing and play tunes at your table. They walk the whole of the River walk.
