Two producers very much under the radar at present are Jacques Greene and Koreless. The two are bright talents forming part of a wider group of exciting producers that the tail end of 2010 and beginning of 2011 has thrown up.
In Canadian Jacques Greene's music there is a more recognisable house influence, contrasting with the dubstep influence present in Koreless's, although two both use brilliant vocal samples and are partial to a 2step beat. There is a warm clean feeling to Koreless's style whereas Greene's tunes carry more dance floor clout.
Both of them have forthcoming releases. Check their respective soundclouds for details.
