- The Casbah in Middletown often has live music performances.

- The Tipsy Crow in the Gaslamp Quarter has karaoke on Thursday nights.

- The Holding Company in Ocean Beach has live music performances and open mic nights.

- The Odysea Lounge in Pacific Beach has karaoke on Friday and Saturday nights.

I hope that helps! Let me know if you have any other questions.
