for blues, besides harvelles in SM & LB. sugar creek mill in tarzana has blues followed by a jam on monday nights.i don’t think harvelles serves food (i’ve never thought to ask there). & sugar creek mill mainly serves burgers, but they get a lot of national acts.i;ve caught kim wilson there.
i DJ blues regularly on sunday nights at joes bar & grill in burbank before (but not during football season), between and after the live blues acts. tomorrow night is paulie cerra - he spent the fall touring with joe bonamassa. in general the live music goes from 8-11pm on sundays. there’s also a dance floor at joes - which is the main reason I DJ there.
viva cantina in burbank has live music but primarily local acts.
the la blues soicety has a page that lists events all over CA, and some of the local blues jams. http://lablues.org/
for live jazz:
vibrato in BH, catalina bar & grill, piano bar in hollywood, blue whale & the edison, maybe villiains in DTLA, pips on la brea, jax in glendale all serve food. but not all of them have jazz every night.
some hotels, especially in BH feature live jazz in their lounges on various nights. ten years ago we used to catch barbara morrison live regularly on friday nights at the four seasons. each of the major BH hotels list an entertainment schedule on their websites.
if you’re on the west side, the casa del mar in SM features live music including jazz depending on the night.
other places that are pasadena friendly would include colombo’s in eagle rock & the barkley in south pasadena which are neighborhood restaurants that feature local acts. when the bands are swing-friendly, you’ll typically see dancers there as well. (which is the main reason i would frequent those places)
