If you're into heavy and dirty psychedelic rock sounds you should maybe consider a trip to Bali which is home to the five guys of Rollfast. The band released some interesting tunes lately resulting in an EP and the most recent "Live At Jizz Studio" recordings.
On three tracks you will get the full psychedelic rock package exept for one thing - clean sounds. The Rollfast approach to the rock genre happens with a maximum of distortion and energy. You will find the classic feedback passages and intense moods over heavy rhythms. Speaking of rhythms, the last song "Destination: Death" combines the echo-loaded jams with a driving stoner sound which makes it a truly heavy piece of rock'n'roll.
