'Noche de fiesta' (1975) was the first album that Julian Angulo and his combo recorded for Colombia's INS label. With arrangements and piano by Alfredo Linares, it's a thrilling LP sought after by collectors and DJs not only for its hard salsa and instrumental "descarga" tracks but also because of the funky dancefloor cuts 'Enyere Kumbara' (covered by Quantic), 'INS-Rock' and 'Estoy soda'.
