Jazz, blues and reggae at Cafe Jazz Populart, Madrid

My old folks listen to jazz music and they usually go to Cafe Jazz Populart (it's located on C. de las Huertas Street no. 22). They told me there are many "young talents" form Madrid and from outside. Besides jazz, you can listen to blues and reggae musicians. The shows begin at 11pm and 00.30am, but the cafe is open from 6pm to 3am. The only inconvenient you might find is the dense smoke.
