Merengada (23 April) and Asere (14 May) at Fiddlers, Bristol. Merengada are 'the UK's only specialist merengue band' and were also responsible for the salsa version of 'No Woman No Cry' - so that's two reasons to stay in ; ) - but Asere should be good.
I'll be in Belfast for a conference, however - and was chuffed to discover that it overlaps with a salsa festival on the 15th/16th. bmibaby fly to Belfast from Cardiff, if anyone else is interested.
