For live music in Rethymno, start with the community events calendar at rethymno.guide and the Municipality agenda, which list concerts at the Fortezza Erofili Theatre, the Municipal Garden and town squares, heaviest from June to September. For traditional Cretan lyra and laouto nights, head to Old Town tavernas and kentra such as the ones known for live evenings, and watch for posters on the lanes, since many sessions are not advertised online. In summer the Fortezza hosts major open air concerts, while bars in the Old Town and along the harbour run rebetiko, jazz and acoustic sets later at night. The simplest method is to walk the Old Town in the early evening, read the posters and ask staff which nights have live music.
