Travis Scott, from Houston, is known for a dark, psychedelic take on trap, with harsh drums and eerie, atmospheric synths. These beats are for artists chasing that heavy, spaced-out sound.
They're mostly trap, most feel dark or epic, and they run faster than the rest of my catalogue. Some carry a psychedelic tag, and some are also tagged Don Toliver or Kid Cudi.
Start with "Insomnia", the most-viewed beat in this set on YouTube.
