The height of the tourist season is also the height of the music season in Santorini. If you are here in July, you may want to take in the annual Santorini Jazz Festival (www.jazzfestival.gr), which has been bringing international jazz bands and artists here since 1997. Many performances are on Kamari beach. In August and September, there's the 2-week Santorini International Music Festival (tel. 22860/23-166), with international singers and musicians, and performances of classical music at the Nomikos Centre, in Fira. Admission to most events starts at 15€.
Fira has all-night nightlife; as always on the islands, places that are hot one season are gone the next. I'm not listing phone numbers here because phones simply are not answered. If you want to kick off your evening with a drink on the caldera as you watch the spectacular sunset, Franco's and Tropical (both on Marinatou St.) are still the most famous spots for this magic hour; be prepared to pay 15€ and up (and up) for a drink. Kira Thira and Koo (two of the wall-to-wall places on Stavrou St.) pack people in later in the day (and through the night). If you are willing to forego the caldera view, you'll find almost too many spots to sample along the main drag and around the main square, including the inevitable Irish pub, Murphy's. Kirathira Bar plays jazz at a level that permits conversation, and the nearby Art Café offers muted music. And don't forget that the island's best restaurant, Selene, now in Pyrgos, has its own cafe bar for a quiet drink and snack.
Discos come and go, and you need only follow your ears to find them. Koo, with at least five different bars, is the biggest; Tithora is popular with a young, heavy-drinking crowd. There's usually no cover, but the cheapest drinks at most places are at least 10€.
Out on the island, in Oia, Zorba's is a popular cliffside pub. The fine Restaurant-Bar 1800 is a quiet, sophisticated place to stop in for a drink and a meal. Kamari Beach has lots of disco bars, including Disco Dom, Mango's, Yellow Donkey, and Valentino's, popular with the youngish tour groupers who grope about here.
